Should I consider other components other than a Denon DCD-600NE CD Player, Spartan 15 MK2 Phono stage and Wiim Ultra?

[Second Opinion]

Background

I bought my Marantz PM80 amplifier and Advent Heritage speakers in the early 1990s and added a 1980s Denon DP1200 direct-drive turntable. They were consigned to the garage in the early 2010s due to various faults. A technician (no longer in business) recommended disposal and replacement.

New system research began a couple of years ago. Rounds of retailer visits and product reviews settled on excellent-sounding components and tower speakers. Before parting with my hard-earned money, I sought advice on product reliability and repairability. A local technician, who has likely been in the industry longer than most and repairs for high-end retailers, provided frank advice. That sent me back to the drawing board to reconsider my selections. There’s no point in spending thousands on a component if it can’t be reasonably repaired out of warranty.

The two best pieces of advice I received during this journey were as follows. First, avoid having too much fruit under the bonnet (from my mechanic), meaning if one feature fails, it could critically impact the entire system. Risk can be reduced through reasonable component separation. Second, incorporate the deflationary nature of consumer electronics into my selection. Cheaper and better options will continue to trend. Separating digital from analogue components will provide flexibility to adopt improvements.

I was introduced to the vintage market around the same time. Vintage gear made sense to a degree. However, potential maintenance costs combined with purchase prices ruled out that option.

While cleaning out my garage recently, I nearly gave away the old junk components for parts. Reflecting on the enjoyment my Marantz, Advent, and Denon components provided, I decided to seek an alternative repair opinion. The prior technician’s advice was incorrect, and the amplifier, turntable, and speakers were restored and now operate like new.

I’m looking to add a CD player, streamer, phono stage, and new cables and connectors to complement my system.

I’ve decided on a Denon DCD-600NE CD player. I’ve given up on finding a transport that suits all needs, so the compromise is a CD player. The Denon’s components are common, so parts for repairs should be available if needed. I’ll add a Spartan 15 MK2 phono stage, courtesy of advice from this site. I was originally keen on the Bluesound Node Icon streamer but will likely go with the WiiM Ultra unless a reason to reconsider arises. For speaker cables and connectors, I’ll DIY. Speaker cables need to be 4 meters long, so I’ll use Mogami 14 AWG or similar. CIC connectors will be finalized once I have the new components.

I’ve been enjoying experimenting with AI and have recently used Grok. I queried my system and options for advice on system optimization and received the following.

My Hi-Fi Query to Grok

My hi-fi system comprises the following components: Marantz PM80, Denon DP1200 with VM95ML cartridge, and Advent Heritage tower speakers. I’m looking to add the following components to complete my system: Denon DCD-600NE, Spartan 15 Mark 2 phono stage, and WiiM Ultra. I’m open to alternative suggestions around the same price points. The task has two parts. Part 1 is to provide a critical analysis of the selected components relative to available market offerings. Part 2 is to provide setup instructions to optimize the performance of the complete system (existing and proposed components).

Grok’s Response

To address your query, I’ll provide a two-part response as requested. Part 1 will critically analyse the proposed components (Denon DCD-600NE CD player, Spartan 15 Mark 2 phono stage, and WiiM Ultra streamer) relative to comparable market offerings in 2025, focusing on their performance, features, and value within similar price ranges. Part 2 will offer detailed setup instructions to optimize the performance of your complete hi-fi system, integrating both existing (Marantz PM80, Denon DP1200 with VM95ML cartridge, Advent Heritage tower speakers) and proposed components.

Part 1: Critical Analysis of Proposed Components Relative to Market Offerings

1. Denon DCD-600NE CD Player (~$299–$429)

Its limited connectivity makes it less versatile than the Marantz CD6007, which offers better synergy with your PM80. If you’re focused on CD playback and don’t need extra features, the DCD-600NE is a strong choice. For a slight budget stretch, the CD6007 provides superior sound and features.

2. Michael Fidler Spartan 15 MKII Phono Stage (~£360/€440/$490)

Overview: The Spartan 15 MKII, handcrafted by Michael Fidler at Classic Audio Ltd., is a moving magnet (MM) phono stage designed for low noise and precision. It features a dual-stage amplification design with NJM2068 op-amps, ±0.1dB RIAA accuracy, a linear power supply, mono switch, low-frequency crossfeed (100/200Hz settings), and a 3rd-order subsonic filter. It delivers a 78dB signal-to-noise ratio and a 550mV output from a 5mV cartridge.

Strengths:

• Sound Quality: Reviewers describe it as exceptionally neutral, with sharp transients, clean bass, and no coloration, outperforming pricier units like the Moon 110LP v2 (~$600). It reveals details in familiar records, enhancing your VM95ML cartridge’s dynamics.
• Low Noise: The 78dB signal-to-noise ratio and linear power supply minimize hum and electrical interference, ensuring a quiet background. The through-hole circuitry and hand-selected components enhance durability and performance.
• Features: The mono switch reduces surface noise on mono records, and the low-frequency crossfeed (100/200Hz) cancels vertical noise, improving bass clarity without sacrificing stereo imaging above the crossover. The subsonic filter prevents infrasonic distortion.
• Value: At ~$490, it’s competitively priced for a handmade UK product, offering performance rivaling phono stages costing twice as much.

Weaknesses:

• MM-Only: Supports only MM cartridges, limiting future upgrades to moving coil (MC) cartridges without additional equipment.
• Aesthetics: The aluminum enclosure is sturdy but plain, lacking the premium look of some competitors.
• Adjustability: Lacks gain or capacitance adjustments, which could fine-tune performance for specific cartridges. Fixed 40.8dB gain may not suit high-output MC cartridges.
• Availability: Limited production due to Michael Fidler’s solo operation may lead to wait times.

Market Alternatives:

• Cambridge Audio Alva Duo (~$349): Supports MM and MC cartridges, providing flexibility for upgrades. Its punchy sound is less neutral than the Spartan 15 MKII.
• Schiit Mani 2 (~$299): Highly adjustable with MM/MC support and variable gain. It’s cheaper and versatile but less refined and neutral than the Spartan.

Analysis: The Spartan 15 MKII is a standout for MM cartridge users, delivering class-leading neutrality and low noise. Its mono switch and crossfeed are unique features, ideal for vintage mono records or noisy pressings. Compared to the Rega Fono MM MK5, it’s more transparent but less warm, which suits your VM95ML’s detailed nature. The Cambridge Alva Duo and Schiit Mani 2 offer MC support, but their sound is less precise. Given your Marantz PM80 likely has a built-in phono stage, test it against the Spartan 15 MKII. The WiiM Ultra’s phono stage (below) may also suffice, potentially making the Spartan redundant unless you prioritize its superior clarity.

3. WiiM Ultra Streamer (~$329)

Overview: The WiiM Ultra is a network streamer, DAC, preamp, and MM phono stage with a Sabre DAC, supporting 24-bit/192kHz audio. It offers extensive connectivity (HDMI ARC, RCA, optical, coaxial, USB, Ethernet, headphone jack), major streaming services, and multi-room audio via its app.

Strengths:

• Versatility: Integrates analog (phono) and digital sources, with HDMI ARC for TV connectivity. It’s a central hub for your system.
• Sound Quality: Produces clear, slightly warm sound for streaming and CD playback (via optical). The Sabre DAC performs well for the price.
• Usability: Intuitive app, voice-activated remote, and display enhance user experience. Supports high-resolution streaming (Tidal, Qobuz).
• Value: At $329, it’s feature-rich compared to pricier streamers like the Bluesound Node ($599).

Weaknesses:

• Phono Stage: The MM phono stage is functional but less detailed and dynamic than dedicated units like the Spartan 15 MKII, described as “cloudy” in reviews.
• Headphone Amp: Adequate for casual use but underpowered for high-impedance headphones.
• DAC: While good, it’s outclassed by dedicated DACs or streamers like the Cambridge Audio MXN10 for pure digital audio.

Market Alternatives:

• Cambridge Audio MXN10 (~$349): A dedicated streamer with a superior DAC, offering cleaner sound for streaming. Lacks phono stage, HDMI ARC, and broad connectivity.
• Bluesound Node (~$599): Premium streamer with a refined DAC and AirPlay. No phono stage or HDMI ARC, and it’s pricier.
• iFi Zen Stream (~$399): High-quality DAC and hi-res streaming but lacks phono stage or HDMI, focusing solely on digital audio.

Analysis: The WiiM Ultra’s versatility makes it a strong addition, handling streaming, CD playback (via optical), and vinyl (via its phono stage). Its sound is engaging, though its phono stage doesn’t match the Spartan 15 MKII’s transparency. Compared to the Cambridge Audio MXN10, it trades some streaming purity for broader functionality. If the WiiM Ultra’s phono stage meets your needs, it could replace the Spartan 15 MKII, saving cost and simplifying your setup.

Recommendation Summary:

• Denon DCD-600NE: Reliable for CD playback, but the Marantz CD6007 offers better sound and synergy with your PM80 if budget allows.
• Spartan 15 MKII: Exceptional for MM cartridges, with unmatched neutrality and unique features. Compare it to the PM80 and WiiM Ultra’s phono stages; it’s likely superior but may be overkill if the others suffice.
• WiiM Ultra: A versatile hub with strong value. Its phono stage may reduce the need for the Spartan 15 MKII if you prioritize connectivity over vinyl purity.

Part 2: Setup Instructions to Optimize Performance

To optimize your hi-fi system, integrating the Marantz PM80, Denon DP1200 with VM95ML cartridge, Advent Heritage tower speakers, Denon DCD-600NE, Spartan 15 MKII, and WiiM Ultra, follow these steps to minimize interference, ensure clean signal paths, and balance the system’s tonal characteristics.

1. Physical Setup

• Placement:
  • Amplifier (Marantz PM80): Place on a sturdy, vibration-resistant rack with 4–6 inches of clearance for heat dissipation. Avoid stacking components on top to prevent interference.
  • CD Player (Denon DCD-600NE): Position on a separate shelf or vibration-damping pads (e.g., Sorbothane feet) to minimize vibrations from speakers or the turntable. Keep it away from the amplifier to reduce electrical noise.
  • Turntable (Denon DP1200): Place on a dedicated, level platform or wall-mounted shelf to isolate it from speaker vibrations. Ensure it’s distant from the Advent Heritage speakers to prevent acoustic feedback.
  • Phono Stage (Spartan 15 MKII): Position near the turntable (within 1 meter) to minimize cable length. Keep it away from power cables, the amplifier, and the WiiM Ultra to avoid hum, as its linear power supply is sensitive to interference.
  • Streamer (WiiM Ultra): Place near the amplifier for short cable runs. Ensure good Wi-Fi/Ethernet access for streaming.
  • Speakers (Advent Heritage): Position 6–10 feet apart, toed-in slightly toward the listening position, forming an equilateral triangle with your seat. Keep them 1–2 feet from the back wall and 3 feet from side walls to balance bass. Elevate tweeters to ear level using stands or furniture. Experiment to tame their bright treble.
• Room Acoustics:
  • Use rugs, curtains, or acoustic panels to dampen reflections in “live” rooms, as the Advent Heritage’s treble can be fatiguing.
  • Ensure a clear path between speakers and listening position for optimal imaging.

2. Connections

• Turntable to Phono Stage:
  • Connect the Denon DP1200’s RCA cables and ground wire to the Spartan 15 MKII’s RCA inputs and ground terminal. Use shielded RCA cables (e.g., Mogami or AudioQuest) to minimize noise.
  • Connect the Spartan 15 MKII’s RCA outputs to a line-level input on the Marantz PM80 (e.g., AUX or TAPE IN), not the phono input, to avoid double amplification.
  • Alternative: If testing the WiiM Ultra’s phono stage, connect the DP1200’s RCA and ground to the WiiM Ultra’s phono input, then route its RCA outputs to the PM80’s AUX input. Compare both phono stages for clarity and dynamics.
• CD Player to Amplifier:
  • Connect the Denon DCD-600NE’s RCA analogue outputs to a line-level input on the Marantz PM80 (e.g., CD or AUX) using shielded RCA cables (e.g., Blue Jeans Cable).
  • Alternative: For potentially warmer sound, connect the DCD-600NE’s Toslink optical output to the WiiM Ultra’s optical input, then route the WiiM Ultra’s RCA outputs to the PM80’s AUX. Test both setups to compare the DCD-600NE’s DAC vs. the WiiM Ultra’s Sabre DAC.
• Streamer to Amplifier:
  • Connect the WiiM Ultra’s RCA outputs to a line-level input on the Marantz PM80 (e.g., TAPE or AUX) with high-quality RCA cables.
  • Connect the WiiM Ultra to your network via Ethernet (preferred) or Wi-Fi. Ensure a strong signal with a router or Wi-Fi extender.
• Speakers to Amplifier:
  • Connect the Advent Heritage speakers to the Marantz PM80’s speaker terminals using 16-gauge or thicker copper cables (e.g., Monoprice). Ensure correct polarity (positive to positive, negative to negative).
  • Use only one set of speaker outputs (A or B) to maintain proper impedance, as the Advent Heritage is likely 6–8 ohms.
• Power:
  • Use a quality power strip or conditioner (e.g., Furman) to reduce noise. Plug the Spartan 15 MKII’s linear power supply into a separate outlet or filtered socket to avoid interference from other components.
  • Keep power cables separate from audio cables to minimize crosstalk.

3. Configuration

• Turntable:
  • Level the Denon DP1200 using a bubble level. Set the tonearm counterweight for a tracking force of 1.8–2.2g for the VM95ML cartridge (per Audio-Technica specs).
  • Adjust anti-skate to match the tracking force (~2g). Align the cartridge using a Baerwald protractor for optimal tracking.
  • Inspect the VM95ML stylus; replace if it has 500–1000 hours of use to preserve detail and protect records.
• Phono Stage (Spartan 15 MKII or WiiM Ultra):
  • Spartan 15 MKII: No gain or capacitance adjustments are needed, as it’s optimized for standard MM cartridges like the VM95ML (4mV output, 47kΩ load). Engage the mono switch for mono records to reduce surface noise. Use the low-frequency cross feed (100Hz for subtle effect, 200Hz for stronger noise reduction) on noisy stereo records to enhance bass clarity.
  • WiiM Ultra: Set the input to “Phono” in the app if using its phono stage. No adjustments are available, so ensure the VM95ML’s output matches its fixed settings.
• CD Player:
  • Use Pure Direct Mode on the DCD-600NE during critical listening to bypass the display and reduce interference.
  • Clean CDs to minimize errors and store them vertically to prevent warping.
• Streamer:
  • In the WiiM app, set output to “Fixed Volume” if using the PM80’s volume control, or use variable output for finer control. Enable 24-bit/192kHz streaming for Tidal/Qobuz.
  • Apply a slight treble reduction (–1 to –2dB above 8kHz) in the app’s EQ if the Advent Heritage sounds bright with streamed content.
  • Update firmware for optimal performance.
• Amplifier:
  • Use “Source Direct” mode on the Marantz PM80 (if available) to bypass tone controls for the purest signal.
  • Start with flat tone settings. Increase bass (+2–4dB) if the Advent Heritage lacks low-end or reduce treble (–2dB) if harsh.
  • Select the correct input for each component (e.g., CD for DCD-600NE, AUX for WiiM Ultra or Spartan 15 MKII).

4. Optimization Tips

• Speaker Placement: Fine-tune the Advent Heritage’s position and toe-in to optimize soundstage. Small adjustments (1–2 inches) can improve imaging and bass.
• Break-In: Allow the VM95ML and new components 20–50 hours to settle. The Spartan 15 MKII’s hand-assembled circuitry may stabilize over time.
• Cable Management: Organize cables to avoid parallel runs of audio and power cables, reducing interference, especially for the Spartan 15 MKII’s sensitive circuitry.
• Listening Levels: Keep volumes moderate (70–85dB) to avoid treble fatigue from the Advent Heritage.
• Room Correction: If the sound is uneven, use the WiiM app’s EQ or consider a miniDSP with UMIK-1 to address room modes, particularly bass.

5. Testing and Fine-Tuning

• Phono Stage Comparison: A/B test the Spartan 15 MKII, WiiM Ultra, and PM80’s built-in phono stage using the same vinyl track. Note differences in clarity, bass definition, and noise. The Spartan’s neutrality and low noise should stand out.
• DAC Comparison: Compare the DCD-600NE’s analogue output vs. its optical output through the WiiM Ultra’s DAC. The WiiM may sound warmer, while the DCD-600NE is more neutral.
• Source Testing: Play diverse genres (jazz, rock, classical) across vinyl, CD, and streaming to ensure versatility.
• Speaker Phase: Verify speaker wiring polarity to avoid reduced bass or muddled imaging.

6. Maintenance

• Turntable: Clean the VM95ML stylus with a brush or gel cleaner (e.g., DS Audio) after every few records. Re-level the DP1200 periodically.
• Phono Stage: Keep the Spartan 15 MKII’s enclosure dust-free to maintain its cooling and aesthetics.
• CD Player: Use a CD lens cleaner if playback errors occur.
• Speakers: Dust the Advent Heritage grilles and cones gently. Check binding posts for tightness.
• Amplifier: Inspect the PM80 for dust or capacitor wear, as it’s vintage. Consider a professional recap if un-serviced.

Final Notes

Your system, anchored by the Marantz PM80, Denon DP1200 with VM95ML, and Advent Heritage speakers, is robust. Adding the Denon DCD-600NE, Michael Fidler Spartan 15 MKII, and WiiM Ultra creates a versatile setup for vinyl, CDs, and streaming. The Spartan 15 MKII’s exceptional neutrality and low noise make it a top-tier MM phono stage, likely surpassing the PM80 and WiiM Ultra’s phono stages for vinyl playback. The WiiM Ultra’s all-in-one functionality could simplify your setup if its phono stage is adequate, but the Spartan’s performance justifies its inclusion for vinyl enthusiasts. The DCD-600NE is a solid CD player, though the Marantz CD6007 could enhance synergy. Optimize through careful placement, quality cables, and testing to balance the Advent Heritage’s lively treble with the system’s warm, detailed character.

If you have preferences (e.g., vinyl vs. streaming priority, tonal balance), let me know for further refinement.

I would appreciate your comments if there were other components recommended or setup advice before I finalize this project.

Welcome to ASR,

A lot to read......

Short answer to the title of this thread is 'No'

I perceive your choices to be low-risk in terms of performance and prefer WiiM gear for the option to apply Parametric EQ to the signal.

 

[JeremyFife]

@Power Pop 23 put it well

Usual next step to an improved sound is to look at your speakers. Yours look pretty nice though https://www.hifi-classic.net/review/advent-heritage-9.html so I think I'd just enjoy the music

 

[post]

Go with this combo

Audiolab 6000CDT (offers better soundstage) Also Denon and Marantz has low resale value. They're found in ebay and 2nd hand shops everywhere. Owners dont care for them and sell them.
Spartan 15 MK2 Phono stage (no comment, i have no turntable knowledge)
Bluesound Node (more features, many says it has good bass and high sound quality, has the ESS ES9039Q2M SABRE dac)

 

[Sal1950]

I’m looking to add a CD player, streamer, phono stage, and new cables and connectors to complement my system.

I’ve decided on a Denon DCD-600NE CD player. I’ve given up on finding a transport that suits all needs, so the compromise is a CD player.

Firstly why mess about with a mostly obsolete CD only component?
For the same money and equal sound quality, there are a number of BluRay players available. They can do everything a CD player can, while also offering fairly future proofed use for video playback, multich/Atmos music playback, streaming apps, and so much more.. I do recommend either the Panasonic DP-UB820-K do to it offering a front panel display which most other modern BD's leave out, or include a small monitor for displaying of the playback functions..

If you are looking for a dedicated streamer, I can highly recommend the Apple 4k TV. An excellent high playback quailty streamer that again offers some future-proofing in its multich app, etc. Time marches on and multich music playback far exceeds what 2ch can offer in a immersive listening experience.

Forget the messing about with vinyl playback, it's been obsolete for 50 some years now with the various digital offerings far exceeding old "snap, crackle, and pop'' for quality music playback in the home.. It's 5x more expensive than the digital offerings for far less in sound quality and extreme inconvenience.
Use the money saved from ignoring vinyl to consider expanding into multich playback. A nice 5.1 rig can take you miles beyond basic 2ch playback, with some overhead Atmos speakers bringing an exciting 3D soundscape to the music.

The PM80 got a decend phono stage, I think you will be extremely disapointed when you compare it to the expensive Spartan 15. Your expectations will not be fullfiled, not even a fraction of them. Sound will not be worse or better, but at best may have subtile, hard to point out difference. You may not even be able to reproduce them, depending on your daily mood. In an objective comparison, you may like the build in Marantz phono stage even more, as those engineers knew their job. Honestly, there has been no development in RIAA phono pre amps for 4 decades. Only marketing and flowery reviewer language have evolved. If you go for the WiiM ultra, you even got a second quality phono pre to compare. Instead of wasting it on a pre, save the money for a better pick up, it will give you a real improvement for your analog phono.
Do not expect any improvement from any cable you buy. If a good,low cost standard product is used, you will get 100% sound quality. If you went to your math lessons, you will know there is no more than 100% of a thing. So even the most expensive wires will not be able to give you 101% sound. If people tell you to "fine tune" the sound with cables, don't listen. If a cable audible changes the sound, it is no wire, but a capacitor or resistor or an ugly combination of both, made to deform the signal.

For the CD player, this is a sad story. The best of them today are used and from some source like eBay or more expensive, from some specialized dealer. The ones sold new all are based on computer DVD or CD units, slow and often noisy, because "real" audio CD drives are not made any more. If you need to buy new, better get a Blueray and use its digital out. You got an excelent DAC in the WiiM ultra, would be stupid not to use it. People that tell you a digital drive will matter are the same that sell you golden network, USB and even power cables. They only want your best, your money. Ironic if you listen to Dire Straighs over a 250$ USB cable: Money for Nothing.

Maybe not what you expected to read, but this is the money saving, sound improving, bloody truth.

My advice would be to avoid Grok, buy any modern or used CD/DVD/Bluray/4K player you like, and get the Wiim Ultra.
I haven't bothered with vinyl playback since my last turntable was stolen about 30 years ago, so no opinion there.

 

[Sal1950]

The Sony X800M2 is an excellent BluRay player with tank like build, and a smooth, quiet transport. $300
I've been very impressed with mine for a couple years now.
It's only drawback is the lack of a display but a tiny unobtrusive 10" or smaller screen can be added for under
$100 if you don't already have something laying around.

 

[DSJR]

If like me, the OP has a good sized vinyl collection, I'd respectfully suggest sorting and updating (possibly with a modern cartridge and siting revision?) the turntable 'system,' using the digital side as a superior source as said here above. The Spartan 15mk2 would be very difficult to better at *any* price I'd suggest, apart from casework to please wealthy people looking at 'eye-fi' and higher price tags. The Marantz though, should have at least an 'adequate' phono section - I don't know what cartridge the OP has.

(I have 'Choice reviews of the 84 and 64 amps, but not the 80 and neither are as 'accurate' in RIAA correction as many of today's stages such as the Spartan, but whether you'd notice I don't know)

The Denon deck, ideally, should be used with lid removed and the thing sited well away from room corners and the speakers themselves, preferably on a rigid support (extremes, either a lightweight one or a paving slab to taste...).

Digital is a done deal, but still, stick to known trusted makes - the Wiim should be fine and I believe it's available via dealers too. Vinyl? Well, it's a paradise for odd-ball tweakers like me to this day, but use digital as the ultimate reference over a range of different albums as it really IS as close to the master recording as the mastering engineer will allow and arguably the best we have domestically....

I don't know the speakers, but if they're still good enough, they'll show the improvement a decent digital source can provide and should also help you sort the vinyl side as best as you can - a good stylus profile and modern phono stage with ample 'headroom/overload margin' seems to minimise the worst effects of ticks and snaps and if they're quiet, they're not adding to the surface noise endemic to the format which a modern stylus profile should (and does) keep low enough.

 

[OldHvyMec]

Wow, that is quite a post. I read the first line.

I use McIntosh and I quit worrying about anything years ago until I went to class DS, bought a streamer, and of course, the occasional turntable from time to time. Thoren TD-121 or 124s, Russcos/QRKs, Sparta, a few Garrard, 401s and 301s. Just for fun.

I just bought a McIntosh C53 because I wanted one. It hasn't even been pulled out of the box.

All the Mac stuff has good dual TT preamps built in. I'm a valve guy, so there are quite a few valve-based phono preamps at my home. Herron, Mcintosh, Decware (for my RtR/TT) DIY, STI, and at least 1/2 dozen others.

CDs/Streamer/Server Cocktail X45. Wonderful little gadget. A lot of my older 78s are on the Server that has a GOOD phono stage to use to record from or to.

Speakers are all 15-50 years old. A lot of DIY, VMPS, and Infinity.

52 years now with Mcintosh. ONE C2500 lost a channel, and that was my fault. 56 pieces at last count. Over 1/2 are vintage and have gone up 500% in many cases.

All the other crap I've bought that died (every AVR I've ever owned are on a pallet in the shop.) JUNK! Every one of them. Denon, Marantz, and a few more. There is one exception: I have an HK that is well over 30 years old that still works. HK HT7.1 (75 wpc) LOL

I'm an AVP guy if I use any multi-channel. Krell, Mcintosh both hold up very well. BUT I like tone controls that are EASY to see and get at.
BTW, NO DSP in my setup. ZERO need. I use room treatment and usually a stereo setup. 2.2/4. 2 mains, 2 bass towers, 2-4 subs. PERFECT for me.

I did buy a mini HT8 for a speaker build, though. Pretty nice considering. I only bought it because it was XLR, and the amps I'm going to use are also.

So McIntosh AVP and a few class Ds, and you're up and going, TT take your pick. It's the cart/Tonearm/phone preamp that is the key anyway, along with proper tonearm cabling.

Regards

Background

I bought my Marantz PM80 amplifier and Advent Heritage speakers in the early 1990s and added a 1980s Denon DP1200 direct-drive turntable. They were consigned to the garage in the early 2010s due to various faults. A technician (no longer in business) recommended disposal and replacement.

I’m looking to add a CD player, streamer, phono stage, and new cables and connectors to complement my system.

I’ve decided on a Denon DCD-600NE CD player. I’ve given up on finding a transport that suits all needs, so the compromise is a CD player. The Denon’s components are common, so parts for repairs should be available if needed. I’ll add a Spartan 15 MK2 phono stage, courtesy of advice from this site. I was originally keen on the Bluesound Node Icon streamer but will likely go with the WiiM Ultra unless a reason to reconsider arises. For speaker cables and connectors, I’ll DIY. Speaker cables need to be 4 meters long, so I’ll use Mogami 14 AWG or similar. CIC connectors will be finalized once I have the new components.

I’ve been enjoying experimenting with AI and have recently used Grok. I queried my system and options for advice on system optimization and received the following.

Part 2: Setup Instructions to Optimize Performance

To optimize your hi-fi system, integrating the Marantz PM80, Denon DP1200 with VM95ML cartridge, Advent Heritage tower speakers, Denon DCD-600NE, Spartan 15 MKII, and WiiM Ultra, follow these steps to minimize interference, ensure clean signal paths, and balance the system’s tonal characteristics.

1. Physical Setup

• Placement:
  • Amplifier (Marantz PM80): Place on a sturdy, vibration-resistant rack with 4–6 inches of clearance for heat dissipation. Avoid stacking components on top to prevent interference.
  • CD Player (Denon DCD-600NE): Position on a separate shelf or vibration-damping pads (e.g., Sorbothane feet) to minimize vibrations from speakers or the turntable. Keep it away from the amplifier to reduce electrical noise.
  • Turntable (Denon DP1200): Place on a dedicated, level platform or wall-mounted shelf to isolate it from speaker vibrations. Ensure it’s distant from the Advent Heritage speakers to prevent acoustic feedback.
  • Phono Stage (Spartan 15 MKII): Position near the turntable (within 1 meter) to minimize cable length. Keep it away from power cables, the amplifier, and the WiiM Ultra to avoid hum, as its linear power supply is sensitive to interference.
  • Streamer (WiiM Ultra): Place near the amplifier for short cable runs. Ensure good Wi-Fi/Ethernet access for streaming.
  • Speakers (Advent Heritage): Position 6–10 feet apart, toed-in slightly toward the listening position, forming an equilateral triangle with your seat. Keep them 1–2 feet from the back wall and 3 feet from side walls to balance bass. Elevate tweeters to ear level using stands or furniture. Experiment to tame their bright treble.
• Room Acoustics:
  • Use rugs, curtains, or acoustic panels to dampen reflections in “live” rooms, as the Advent Heritage’s treble can be fatiguing.
  • Ensure a clear path between speakers and listening position for optimal imaging.

2. Connections

• Turntable to Phono Stage:
  • Connect the Denon DP1200’s RCA cables and ground wire to the Spartan 15 MKII’s RCA inputs and ground terminal. Use shielded RCA cables (e.g., Mogami or AudioQuest) to minimize noise.
  • Connect the Spartan 15 MKII’s RCA outputs to a line-level input on the Marantz PM80 (e.g., AUX or TAPE IN), not the phono input, to avoid double amplification.
  • Alternative: If testing the WiiM Ultra’s phono stage, connect the DP1200’s RCA and ground to the WiiM Ultra’s phono input, then route its RCA outputs to the PM80’s AUX input. Compare both phono stages for clarity and dynamics.
• CD Player to Amplifier:
  • Connect the Denon DCD-600NE’s RCA analogue outputs to a line-level input on the Marantz PM80 (e.g., CD or AUX) using shielded RCA cables (e.g., Blue Jeans Cable).
  • Alternative: For potentially warmer sound, connect the DCD-600NE’s Toslink optical output to the WiiM Ultra’s optical input, then route the WiiM Ultra’s RCA outputs to the PM80’s AUX. Test both setups to compare the DCD-600NE’s DAC vs. the WiiM Ultra’s Sabre DAC.
• Streamer to Amplifier:
  • Connect the WiiM Ultra’s RCA outputs to a line-level input on the Marantz PM80 (e.g., TAPE or AUX) with high-quality RCA cables.
  • Connect the WiiM Ultra to your network via Ethernet (preferred) or Wi-Fi. Ensure a strong signal with a router or Wi-Fi extender.
• Speakers to Amplifier:
  • Connect the Advent Heritage speakers to the Marantz PM80’s speaker terminals using 16-gauge or thicker copper cables (e.g., Monoprice). Ensure correct polarity (positive to positive, negative to negative).
  • Use only one set of speaker outputs (A or B) to maintain proper impedance, as the Advent Heritage is likely 6–8 ohms.
• Power:
  • Use a quality power strip or conditioner (e.g., Furman) to reduce noise. Plug the Spartan 15 MKII’s linear power supply into a separate outlet or filtered socket to avoid interference from other components.
  • Keep power cables separate from audio cables to minimize crosstalk.

3. Configuration

• Turntable:
  • Level the Denon DP1200 using a bubble level. Set the tonearm counterweight for a tracking force of 1.8–2.2g for the VM95ML cartridge (per Audio-Technica specs).
  • Adjust anti-skate to match the tracking force (~2g). Align the cartridge using a Baerwald protractor for optimal tracking.
  • Inspect the VM95ML stylus; replace if it has 500–1000 hours of use to preserve detail and protect records.
• Phono Stage (Spartan 15 MKII or WiiM Ultra):
  • Spartan 15 MKII: No gain or capacitance adjustments are needed, as it’s optimized for standard MM cartridges like the VM95ML (4mV output, 47kΩ load). Engage the mono switch for mono records to reduce surface noise. Use the low-frequency cross feed (100Hz for subtle effect, 200Hz for stronger noise reduction) on noisy stereo records to enhance bass clarity.
  • WiiM Ultra: Set the input to “Phono” in the app if using its phono stage. No adjustments are available, so ensure the VM95ML’s output matches its fixed settings.
• CD Player:
  • Use Pure Direct Mode on the DCD-600NE during critical listening to bypass the display and reduce interference.
  • Clean CDs to minimize errors and store them vertically to prevent warping.
• Streamer:
  • In the WiiM app, set output to “Fixed Volume” if using the PM80’s volume control, or use variable output for finer control. Enable 24-bit/192kHz streaming for Tidal/Qobuz.
  • Apply a slight treble reduction (–1 to –2dB above 8kHz) in the app’s EQ if the Advent Heritage sounds bright with streamed content.
  • Update firmware for optimal performance.
• Amplifier:
  • Use “Source Direct” mode on the Marantz PM80 (if available) to bypass tone controls for the purest signal.
  • Start with flat tone settings. Increase bass (+2–4dB) if the Advent Heritage lacks low-end or reduce treble (–2dB) if harsh.
  • Select the correct input for each component (e.g., CD for DCD-600NE, AUX for WiiM Ultra or Spartan 15 MKII).

4. Optimization Tips

• Speaker Placement: Fine-tune the Advent Heritage’s position and toe-in to optimize soundstage. Small adjustments (1–2 inches) can improve imaging and bass.
• Break-In: Allow the VM95ML and new components 20–50 hours to settle. The Spartan 15 MKII’s hand-assembled circuitry may stabilize over time.
• Cable Management: Organize cables to avoid parallel runs of audio and power cables, reducing interference, especially for the Spartan 15 MKII’s sensitive circuitry.
• Listening Levels: Keep volumes moderate (70–85dB) to avoid treble fatigue from the Advent Heritage.
• Room Correction: If the sound is uneven, use the WiiM app’s EQ or consider a miniDSP with UMIK-1 to address room modes, particularly bass.

5. Testing and Fine-Tuning

• Phono Stage Comparison: A/B test the Spartan 15 MKII, WiiM Ultra, and PM80’s built-in phono stage using the same vinyl track. Note differences in clarity, bass definition, and noise. The Spartan’s neutrality and low noise should stand out.
• DAC Comparison: Compare the DCD-600NE’s analogue output vs. its optical output through the WiiM Ultra’s DAC. The WiiM may sound warmer, while the DCD-600NE is more neutral.
• Source Testing: Play diverse genres (jazz, rock, classical) across vinyl, CD, and streaming to ensure versatility.
• Speaker Phase: Verify speaker wiring polarity to avoid reduced bass or muddled imaging.

6. Maintenance

• Turntable: Clean the VM95ML stylus with a brush or gel cleaner (e.g., DS Audio) after every few records. Re-level the DP1200 periodically.
• Phono Stage: Keep the Spartan 15 MKII’s enclosure dust-free to maintain its cooling and aesthetics.
• CD Player: Use a CD lens cleaner if playback errors occur.
• Speakers: Dust the Advent Heritage grilles and cones gently. Check binding posts for tightness.
• Amplifier: Inspect the PM80 for dust or capacitor wear, as it’s vintage. Consider a professional recap if un-serviced.

Final Notes

Your system, anchored by the Marantz PM80, Denon DP1200 with VM95ML, and Advent Heritage speakers, is robust. Adding the Denon DCD-600NE, Michael Fidler Spartan 15 MKII, and WiiM Ultra creates a versatile setup for vinyl, CDs, and streaming. The Spartan 15 MKII’s exceptional neutrality and low noise make it a top-tier MM phono stage, likely surpassing the PM80 and WiiM Ultra’s phono stages for vinyl playback. The WiiM Ultra’s all-in-one functionality could simplify your setup if its phono stage is adequate, but the Spartan’s performance justifies its inclusion for vinyl enthusiasts. The DCD-600NE is a solid CD player, though the Marantz CD6007 could enhance synergy. Optimize through careful placement, quality cables, and testing to balance the Advent Heritage’s lively treble with the system’s warm, detailed character.

If you have preferences (e.g., vinyl vs. streaming priority, tonal balance), let me know for further refinement.

I would appreciate your comments if there were other components recommended or setup advice before I finalize this project.

It's funny how queries posted to Grok just end as vastly overlong queries to the ASR community.
Personally I don't find asking AI bots owned by Nazi-saluting Ketamine addicted narcissists questions about gear choices very helpful on my way to audio nirvana.
YMMV.

Background

I bought my Marantz PM80 amplifier and Advent Heritage speakers in the early 1990s and added a 1980s Denon DP1200 direct-drive turntable. They were consigned to the garage in the early 2010s due to various faults. A technician (no longer in business) recommended disposal and replacement.

New system research began a couple of years ago. Rounds of retailer visits and product reviews settled on excellent-sounding components and tower speakers. Before parting with my hard-earned money, I sought advice on product reliability and repairability. A local technician, who has likely been in the industry longer than most and repairs for high-end retailers, provided frank advice. That sent me back to the drawing board to reconsider my selections. There’s no point in spending thousands on a component if it can’t be reasonably repaired out of warranty.

The two best pieces of advice I received during this journey were as follows. First, avoid having too much fruit under the bonnet (from my mechanic), meaning if one feature fails, it could critically impact the entire system. Risk can be reduced through reasonable component separation. Second, incorporate the deflationary nature of consumer electronics into my selection. Cheaper and better options will continue to trend. Separating digital from analogue components will provide flexibility to adopt improvements.

I was introduced to the vintage market around the same time. Vintage gear made sense to a degree. However, potential maintenance costs combined with purchase prices ruled out that option.

While cleaning out my garage recently, I nearly gave away the old junk components for parts. Reflecting on the enjoyment my Marantz, Advent, and Denon components provided, I decided to seek an alternative repair opinion. The prior technician’s advice was incorrect, and the amplifier, turntable, and speakers were restored and now operate like new.

I’m looking to add a CD player, streamer, phono stage, and new cables and connectors to complement my system.

I’ve decided on a Denon DCD-600NE CD player. I’ve given up on finding a transport that suits all needs, so the compromise is a CD player. The Denon’s components are common, so parts for repairs should be available if needed. I’ll add a Spartan 15 MK2 phono stage, courtesy of advice from this site.

  • CD Player (Denon DCD-600NE): Position on a separate shelf or vibration-damping pads (e.g., Sorbothane feet) to minimize vibrations from speakers or the turntable. Keep it away from the amplifier to reduce electrical noise.
  • Turntable (Denon DP1200): Place on a dedicated, level platform or wall-mounted shelf to isolate it from speaker vibrations. Ensure it’s distant from the Advent Heritage speakers to prevent acoustic feedback.
  • Phono Stage (Spartan 15 MKII): Position near the turntable (within 1 meter) to minimize cable length. Keep it away from power cables, the amplifier, and the WiiM Ultra to avoid hum, as its linear power supply is sensitive to interference.
  • Streamer (WiiM Ultra): Place near the amplifier for short cable runs. Ensure good Wi-Fi/Ethernet access for streaming.
  • Speakers (Advent Heritage): Position 6–10 feet apart, toed-in slightly toward the listening position, forming an equilateral triangle with your seat. Keep them 1–2 feet from the back wall and 3 feet from side walls to balance bass. Elevate tweeters to ear level using stands or furniture. Experiment to tame their bright treble.
• Room Acoustics:
  • Use rugs, curtains, or acoustic panels to dampen reflections in “live” rooms, as the Advent Heritage’s treble can be fatiguing.
  • Ensure a clear path between speakers and listening position for optimal imaging.

2. Connections

• Turntable to Phono Stage:
  • Connect the Denon DP1200’s RCA cables and ground wire to the Spartan 15 MKII’s RCA inputs and ground terminal. Use shielded RCA cables (e.g., Mogami or AudioQuest) to minimize noise.
  • Connect the Spartan 15 MKII’s RCA outputs to a line-level input on the Marantz PM80 (e.g., AUX or TAPE IN), not the phono input, to avoid double amplification.
  • Alternative: If testing the WiiM Ultra’s phono stage, connect the DP1200’s RCA and ground to the WiiM Ultra’s phono input, then route its RCA outputs to the PM80’s AUX input. Compare both phono stages for clarity and dynamics.
• CD Player to Amplifier:
  • Connect the Denon DCD-600NE’s RCA analogue outputs to a line-level input on the Marantz PM80 (e.g., CD or AUX) using shielded RCA cables (e.g., Blue Jeans Cable).
  • Alternative: For potentially warmer sound, connect the DCD-600NE’s Toslink optical output to the WiiM Ultra’s optical input, then route the WiiM Ultra’s RCA outputs to the PM80’s AUX. Test both setups to compare the DCD-600NE’s DAC vs. the WiiM Ultra’s Sabre DAC.
• Streamer to Amplifier:
  • Connect the WiiM Ultra’s RCA outputs to a line-level input on the Marantz PM80 (e.g., TAPE or AUX) with high-quality RCA cables.
  • Connect the WiiM Ultra to your network via Ethernet (preferred) or Wi-Fi. Ensure a strong signal with a router or Wi-Fi extender.
• Speakers to Amplifier:
  • Connect the Advent Heritage speakers to the Marantz PM80’s speaker terminals using 16-gauge or thicker copper cables (e.g., Monoprice). Ensure correct polarity (positive to positive, negative to negative).
  • Use only one set of speaker outputs (A or B) to maintain proper impedance, as the Advent Heritage is likely 6–8 ohms.
• Power:
  • Use a quality power strip or conditioner (e.g., Furman) to reduce noise. Plug the Spartan 15 MKII’s linear power supply into a separate outlet or filtered socket to avoid interference from other components.
  • Keep power cables separate from audio cables to minimize crosstalk.

3. Configuration

• Turntable:
  • Level the Denon DP1200 using a bubble level. Set the tonearm counterweight for a tracking force of 1.8–2.2g for the VM95ML cartridge (per Audio-Technica specs).
  • Adjust anti-skate to match the tracking force (~2g). Align the cartridge using a Baerwald protractor for optimal tracking.
  • Inspect the VM95ML stylus; replace if it has 500–1000 hours of use to preserve detail and protect records.
• Phono Stage (Spartan 15 MKII or WiiM Ultra):
  • Spartan 15 MKII: No gain or capacitance adjustments are needed, as it’s optimized for standard MM cartridges like the VM95ML (4mV output, 47kΩ load). Engage the mono switch for mono records to reduce surface noise. Use the low-frequency cross feed (100Hz for subtle effect, 200Hz for stronger noise reduction) on noisy stereo records to enhance bass clarity.
  • WiiM Ultra: Set the input to “Phono” in the app if using its phono stage. No adjustments are available, so ensure the VM95ML’s output matches its fixed settings.
• CD Player:
  • Use Pure Direct Mode on the DCD-600NE during critical listening to bypass the display and reduce interference.
  • Clean CDs to minimize errors and store them vertically to prevent warping.
• Streamer:
  • In the WiiM app, set output to “Fixed Volume” if using the PM80’s volume control, or use variable output for finer control. Enable 24-bit/192kHz streaming for Tidal/Qobuz.
  • Apply a slight treble reduction (–1 to –2dB above 8kHz) in the app’s EQ if the Advent Heritage sounds bright with streamed content.
  • Update firmware for optimal performance.
• Amplifier:
  • Use “Source Direct” mode on the Marantz PM80 (if available) to bypass tone controls for the purest signal.
  • Start with flat tone settings. Increase bass (+2–4dB) if the Advent Heritage lacks low-end or reduce treble (–2dB) if harsh.
  • Select the correct input for each component (e.g., CD for DCD-600NE, AUX for WiiM Ultra or Spartan 15 MKII).

4. Optimization Tips

• Speaker Placement: Fine-tune the Advent Heritage’s position and toe-in to optimize soundstage. Small adjustments (1–2 inches) can improve imaging and bass.
• Break-In: Allow the VM95ML and new components 20–50 hours to settle. The Spartan 15 MKII’s hand-assembled circuitry may stabilize over time.
• Cable Management: Organize cables to avoid parallel runs of audio and power cables, reducing interference, especially for the Spartan 15 MKII’s sensitive circuitry.
• Listening Levels: Keep volumes moderate (70–85dB) to avoid treble fatigue from the Advent Heritage.
• Room Correction: If the sound is uneven, use the WiiM app’s EQ or consider a miniDSP with UMIK-1 to address room modes, particularly bass.

5. Testing and Fine-Tuning

• Phono Stage Comparison: A/B test the Spartan 15 MKII, WiiM Ultra, and PM80’s built-in phono stage using the same vinyl track. Note differences in clarity, bass definition, and noise. The Spartan’s neutrality and low noise should stand out.
• DAC Comparison: Compare the DCD-600NE’s analogue output vs. its optical output through the WiiM Ultra’s DAC. The WiiM may sound warmer, while the DCD-600NE is more neutral.
• Source Testing: Play diverse genres (jazz, rock, classical) across vinyl, CD, and streaming to ensure versatility.
• Speaker Phase: Verify speaker wiring polarity to avoid reduced bass or muddled imaging.

6. Maintenance

• Turntable: Clean the VM95ML stylus with a brush or gel cleaner (e.g., DS Audio) after every few records. Re-level the DP1200 periodically.
• Phono Stage: Keep the Spartan 15 MKII’s enclosure dust-free to maintain its cooling and aesthetics.
• CD Player: Use a CD lens cleaner if playback errors occur.
• Speakers: Dust the Advent Heritage grilles and cones gently. Check binding posts for tightness.
• Amplifier: Inspect the PM80 for dust or capacitor wear, as it’s vintage. Consider a professional recap if un-serviced.

Final Notes

Your system, anchored by the Marantz PM80, Denon DP1200 with VM95ML, and Advent Heritage speakers, is robust. Adding the Denon DCD-600NE, Michael Fidler Spartan 15 MKII, and WiiM Ultra creates a versatile setup for vinyl, CDs, and streaming. The Spartan 15 MKII’s exceptional neutrality and low noise make it a top-tier MM phono stage, likely surpassing the PM80 and WiiM Ultra’s phono stages for vinyl playback. The WiiM Ultra’s all-in-one functionality could simplify your setup if its phono stage is adequate, but the Spartan’s performance justifies its inclusion for vinyl enthusiasts. The DCD-600NE is a solid CD player, though the Marantz CD6007 could enhance synergy. Optimize through careful placement, quality cables, and testing to balance the Advent Heritage’s lively treble with the system’s warm, detailed character.

If you have preferences (e.g., vinyl vs. streaming priority, tonal balance), let me know for further refinement.

I would appreciate your comments if there were other components recommended or setup advice before I finalize this project.

No-one here is going to critique a wall of slop. (Frankly I don't think it should even be allowed here, given that it's going to have been mostly trained on subjective drivel). If you have confidence in it, just use it. If you're after an accurate response then consider posting a question of your own.

Those AI bots read any subjective review and marketing babble and average it to something that sounds quite rationale and objective. Anyway, it is just distilled from 100% snake oiled audio reviews. These are written to keep the vendors paid advertisments on the platform.
So what can you expect from AI? In this case, plain nothing. It is not even worth the energy needed to send the bits over the internet.
It is already bad that AI will soon decide over any aspect of your personal life. Don't enforce the process of getting incapacitated buy a stupid machine.
