AXPONA 2026: Estelon & Vitus $1.5M Audio System

[PristineSound]

Have you asked ChatGTP?

Per ChatGPT Below

Prompt:
"In high fidelity audio equipment, a power cable doesn't carry audio signal. Why do folks say that changes the sound? Please compare their answer with proven science. Please do not use ASR as your source."

ChatGPT's response:
Short answer: a power cable doesn’t carry the audio signal, but it does feed the circuitry that ultimately creates the audio signal. So in principle it can influence sound—but under normal, well-designed conditions the effect should be negligible to nonexistent. The gap between what people report and what’s supported by controlled measurements is where the debate lives.

What enthusiasts typically claim

You’ll hear descriptions like:

“blacker background”

“tighter bass”

“more air and detail”

“better imaging”


The explanations usually fall into a few categories:

1) “Cleaner power”

Claim: Premium cables reduce noise from the wall, improving sound.

Reality check:
Most modern audio gear already includes:

power transformers

rectifiers

large filter capacitors

voltage regulators


These stages provide orders of magnitude more noise reduction than any short AC cable ever could. By the time power reaches the audio circuitry, the waveform from the wall has been heavily transformed into stable DC.


---

2) “Better current delivery / dynamics”

Claim: A thicker or better cable allows faster current delivery for dynamic peaks.

Reality check:
From basic circuit theory (Ohm’s Law):

genui{"math_block_widget_always_prefetch_v2":{"content":"V = IR"}}The resistance of a typical 6-foot power cable is extremely small (milliohms).

The voltage drop across it—even during peaks—is tiny compared to the supply voltage.

The dominant impedance is usually the house wiring and power supply design, not the last few feet of cable.


So unless the cable is defective or absurdly thin, it won’t limit dynamics.


---

3) “Shielding against interference”

Claim: Fancy cables block electromagnetic interference (EMI/RFI).

Reality check:

EMI can matter—but it’s far more effectively handled inside the component (layout, grounding, filtering).

A properly designed power supply already rejects common noise (high PSRR—power supply rejection ratio).

External cable shielding can help in extreme RF environments, but that’s not typical home listening.



---

4) “Directionality / metallurgy / cryogenic treatment”

Claim: Cable materials or direction affect electron flow and thus sound.

Reality check:

AC power alternates direction 50/60 times per second.

Copper conductivity differences at audio-relevant frequencies are negligible.

No established electrical theory predicts audible effects from these factors in power cables.



---

What controlled science says

When tested under controlled conditions (level-matched, blind listening, proper controls):

Differences between competent power cables are generally not detectable

Measured differences (if any) are typically:

far below audible thresholds

buried under the noise floor of the system



Key engineering principles:

Power supply rejection isolates audio circuits from AC variations

Filtering and regulation dominate noise performance

Last-meter effects are negligible compared to upstream wiring and internal design



---

Why people still hear differences

This is the interesting part—and it’s not about dismissing people, but understanding perception.

1) Expectation bias

If you expect improvement (especially after spending money), your brain often finds it.

2) Sighted listening

Knowing which cable is in use changes perception—this is well documented in psychoacoustics.

3) Small uncontrolled variables

Slight volume differences

Replugging connections

Time gaps between comparisons


These can create perceived changes that aren’t from the cable.

4) System interactions (rare but real)

In poorly designed or edge-case systems:

ground loops

RF susceptibility

inadequate power supply design


A different cable might slightly change behavior—but this is fixing a flaw, not revealing hidden fidelity.


---

Where both sides have a point

Audiophile intuition (partially valid):

Power quality can affect audio equipment

Noise and grounding matter


Engineering reality (stronger support):

The power supply design is what determines susceptibility

A normal, spec-compliant cable is already “good enough”

Improvements from cables alone are typically below audibility



---

A useful analogy

Think of it like fueling a car:

The engine (power supply) determines performance

The fuel line (power cable) just needs to not restrict flow


Upgrading the fuel line doesn’t make the engine more powerful—unless the original was faulty.


---

Bottom line

There is no solid, reproducible scientific evidence that standard, properly built power cables change sound quality in normal conditions.

Most claimed differences are better explained by perception, bias, or system issues, not the cable itself.

If a cable does make a difference, it usually points to a problem elsewhere in the system.

If you want, I can walk you through a simple blind test setup that lets you evaluate this objectively with your own system.

 

[kemmler3D]

I will just point out that cables in a studio context (especially for mics) are a different beast than speaker cables in particular. Speaker cables are carrying signals at tens of volts a few feet, mic cables are carrying signals at 0.01-0.001 volt or lower, and in some studios those cables may go dozens of feet or more.

Higher-spec cables may be fully justifiable in a recording context, especially an exceptional professional case like Prince's studio... which doesn't imply anything in particular for someone listening to Prince on his stereo. Do you need the same tool for tasks that vary by orders of magnitude?

Skydivers need goggles, I don't need them to watch Youtube videos of skydiving with my fan on its lowest setting.

 

[amirm]

For me, it’s mostly about rejection of EMI/RFI and having an ultra low internal resistance in the cable.

At the risk of stating the obvious, the human body does not have any way of detecting EMI/RFI. So you have to use instrumentation. What instrumentation did you use to determine you have EMI/RFI that is entering said cable and then going out of the system?

FYI I have tested for this. The only outcome I have found is that some premium cables are worse in this regard than cheap ones.

Here is Nordost Flatline Speaker Cable in presence of strong magnetic field:

And cheap cable:

As to resistance, that is trivially measured. Why is that not a published spec and comparison shown to cheaper cables?

 

[amirm]

I will just point out that cables in a studio context (especially for mics) are a different beast than speaker cables in particular.

Cheap cables follow the requirements for each application just as well. It is the high-end cables that routinely violate some of these things, like unshielded interconnects.

 

[aldolovesmusic]

I don't ask it questions to which I know the answer of. But since you asked, i just tried it:

do power cables improve audio fidelity?

Short answer: no—at least not in the way people often claim.

From an engineering standpoint, once a power cable is adequately built (correct gauge, proper insulation, solid connections), it should deliver AC power to your audio equipment identically to any other compliant cable. The power then goes through the device’s internal power supply, which is specifically designed to regulate voltage, filter noise, and isolate the audio circuitry from imperfections in the incoming AC.

A few grounded points:

• Electrical reality: The last 3–6 feet of cable in your room isn’t magically fixing or transforming the hundreds of feet of standard wiring between your house and the power grid.
• Power supply design: Quality audio gear includes filtering and regulation stages that largely determine performance—not the external cord.
• Audible differences: Controlled, blind listening tests generally show no consistent, repeatable improvement from expensive “audiophile” power cables.
• Where it can matter: Poorly made or damaged cables can cause problems (noise, voltage drop, safety risks). In rare cases with very noisy electrical environments, better shielding or a power conditioner can help—but that’s about noise mitigation, not “enhancing fidelity.”

What does make a real difference:

• Speaker placement and room acoustics
• Quality of speakers/headphones
• Source quality and mastering
• Proper grounding and avoiding interference issues

If you’re chasing better sound, money is almost always better spent on those areas rather than premium power cables.

If you want, tell me your setup—I can suggest upgrades that will actually move the needle.

Now what?

Excellent. I decided to ask more specifics in my question. I’ve had to learn how to effectively use AI like a tool and not a wasteful toy.

Below is my question and the response it gave. Not ideal, but what I’ve been saying about noise rejection is absolutely the most important aspect. That and impedance which is directly related to IR (internal resistance). Also capacitance plays a role.

If I have an ultra high resolution, high performance audio system for two channel listening and I want to try different power cables in my system, are some power cables better than others in conductivity, noise rejection, or other aspects than can and would change or alter sound? Please elaborate.

Short answer: yes, power cables can differ measurably in electrical behavior, but whether those differences rise to the level of audible changes in a well-designed high-end system is far more nuanced—and often much smaller than many expect.


Given the level of resolution in your system (Estelon Extreme MkII, dedicated power, grounding scheme, etc.), you’re in the category where small changes can sometimes be exposed—but they still need to survive some hard physics.


Let’s break it down cleanly.





1.


Conductivity: largely a non-issue (within reason)


Power cables are short runs relative to your house wiring. Even a “standard” 14 AWG copper cable has extremely low resistance over 6–10 feet.

• Copper vs silver:
  • Silver is ~5–6% more conductive than copper
  • Over a short power cable, this translates to negligible voltage drop differences
• “Infinite crystal,” OCC, etc.:
  • These reduce grain boundaries (relevant in signal cables at very low voltages)
  • For 50/60 Hz AC power delivery, this has no meaningful impact on current delivery

Bottom line:
Conductivity differences in power cables are not what changes sound in any meaningful way.





2.


Where differences can exist: impedance & current delivery


What can vary:

• Contact resistance (connectors, terminations)
• Cable geometry affecting inductance
• Shielding and ground interaction

In amplifiers—especially high-current designs—this can influence:

• Transient current draw
• Micro voltage stability under load

But:

• Your dedicated 100A subpanel + low impedance grounding (~2Ω) already dominates performance here
• The last 6 feet of cable is a small part of a much larger power delivery chain

Audible impact: possible, but typically subtle and system-dependent





3.


Noise rejection & EMI/RFI: the real battleground


This is where power cables can legitimately differ.


Sources of noise:

• WiFi, switching supplies, LED drivers (you have many)
• Household appliances
• External RF

Cable design factors:

• Shielding (foil, braid, hybrid)
• Twisted conductors (common-mode noise rejection)
• Ground shielding strategy (floating vs tied ends)

What matters:

• Preventing RF from entering sensitive components
• Especially:
  • DACs
  • preamps
  • phono stages

However—and this is critical:


Most well-designed high-end audio components already include power supply filtering, regulation, and rejection far superior to what a cable can do.


So:

• A cable can help reduce noise ingress
• But it’s working upstream of much stronger internal filtering

4.


Shielding: double-edged sword


Highly shielded cables can:


✔ Reduce RF ingress
Increase capacitance and potentially alter ground behavior


In some systems, this can:

• Lower noise floor slightly
• Or… create ground loops or subtle tonal shifts

This is why people report:

• “Blacker background” vs
• “Softer dynamics” or “less life”

Both can be true depending on implementation.





5.


Mechanical & connector quality (underrated factor)


This often matters more than exotic metallurgy:

• Tight, high-pressure connections = lower contact resistance
• Better materials (copper alloys vs brass) reduce micro-arcing
• Vibration control (yes, real—but minor)

Poor connections can absolutely degrade performance
Good connectors can outperform exotic wire





6.


System-dependent audibility


In your specific system:


You already have:

• Dedicated power infrastructure
• Star grounding
• Extremely resolving speakers
• Carefully controlled acoustics

That means:

• You’ve eliminated the big problems already
• Remaining differences from cables = fine tuning at the margins

If differences are heard, they are typically:

• Noise floor shifts (very subtle)
• Microdynamic contrast
• Perceived tonal balance (often due to noise spectrum, not frequency response)

7.


Expectation vs physics


Here’s the honest pushback:

• Many reported differences between power cables are larger than what physics predicts
• That doesn’t mean people are lying—but:
  • Human perception is extremely context-sensitive
  • Small level differences or noise changes can be interpreted as tonal changes

8.


What actually moves the needle more


In your room/system, these dominate over power cables:

• Speaker placement & phase alignment (you’ve been working this deeply)
• Low-frequency modal control (your aperiodic membrane system)
• Grounding topology (you’ve optimized this heavily)
• Component power supply design (Vitus-level gear is already exceptional)

9.


Practical recommendation (for your system)


If you want to experiment intelligently:

• Try one cable at a time on:
  • DAC
  • preamp
  • amp (last, not first)
• Focus on:
  • Shielded vs unshielded differences
  • Connector quality
• Avoid:
  • Overbuilt, ultra-high capacitance designs
• Keep:
  • Consistent grounding scheme

And most importantly:

• Level match and blind test if possible

Bottom line

• Yes, power cables can differ in shielding, impedance, and construction
• No, conductivity and “crystal structure” are not meaningful factors for AC power
• Audible differences, if present, are typically small and system-dependent
• In a system like yours, they act as fine tuning tools—not performance upgrades

Hi @aldolovesmusic , you mentioned a couple of times that you are an acoustical engineer. Can you share your academic background with us along with any relevant professional training you may have?

 

[amirm]

I decided to ask more specifics in my question. I’ve had to learn how to effectively use AI like a tool and not a wasteful toy.

And that was your mistake. Clearly AI had kept track of your past questions, e.g. knew your system, and hence, told you what you wanted to hear. As a repeater of what is written out there, AI has no trouble finding countless claims of audible differences in cables, such as what you wrote to draw upon based on what you asked it. After all, it is all a correlation engine. The most likely answer to the words used in the question, past and current present.

I specifically did NOT login into my account on ChatGPT for that reason. Still, it correctly guessed that I didn't want to read nonsense about cables and gave that correct answer.

Conclusion: please don't use ChatGPT for such things. In all cases, you need to know more than it to know if the answers are right or wrong.

 

[Beave]

Hi Duke, thanks for your kind words and comments. The sound was my taste, which isn’t for everyone. It was indeed relaxed, but hyper detailed and dynamic with life-like and live transients with fast decay, big soundstage that was deep, wide, and tall, and layered in a 3 dimensional presence. Those Crystal Cable Infinite Dream cables were key to get hyper detailed sound with fast transients that were also presented in a relaxed and luxurious way.

I was at FLAX in Tampa. I setup the Forza speakers in that crazy room for House of Stereo and Estelon. Most people didn’t know, but that room is 53’ deep. I had the speakers 19 feet from the front wall and had the drapes placed just 5 feet from the drapes. Since the room was so long and only 16’ wide, it was necessary to setup the speakers this way to get proper bass energy and phasing at the first room for the listener area. However, the second row was 6dB up at 40Hz, back row 12dB up, and 18dB up if standing near the rear wall.

If anybody was wondering why his posts about cables read more like marketing blurbs than actual science:


https://www.cepro.com/briefs/crystal-cable-sales-now-handled-by-elite-marketing/123763/

I wonder when the ultra rich buys these expensive cables, do they buy it because they believe the psuedoscience that's being sold to them?

Or is it because they are so rich, they're like "what is $10k for a pair of speaker cable anyway, who cares if they make a difference or not, I got so much money, it's weighing my pants down so I need to get rid of some coins."

I wonder what the ultra rich techies like Elon Musk or Jensen Huang do, do they buy expensive cables?

I have so many questions about the people who buy these expensive cables.

But you are trying to spread FUD about certain cables making audiability differences when there basically is no physical mechanism for it to happen and even sell such cables in your professional life ? It’s representative of much of what’s actually wrong with this business.

If you want to be a positive contributor to audio culture, ditch the snakeoil products

Yes just representing such products are a bit insulting to for example me ( it goes both ways you now ) it’s akin to sell fake cancer medicine or any other snakeoil practices that’s all to common in this world .

[Mart68]

One thing we all need to understand, consider, and agree on is that the acoustical environment is super critical to the end result sound you attain. If you have not properly addressed acoustics with an acoustical engineer that specializes in HiFi applications, and the room is properly treated, they you are experiencing multitudes of phase distortion, comb filtering, temporal smearing, edge distractions, Haas effects (negatively), and various bass modes. ALL of these will mask fine details as well as can greatly compromise an otherwise wonderful system. In these cases, swapping cables might make little or no difference.

And yet people who have poor quality speakers, badly set up in whatever cubby hole their wives have allowed them to use, with no acoustic treatment let alone an acoustical engineer on standby, still perceive cable differences and still spend significant money on cables - speaker cables, interconnects for both analogue and digital, and power.

And they all say the same things 'Wife heard the difference, difference was night and day, reverting back to the old cable the system sounded broken' etc.

Demonstrating that it's cognitive bias, not exceptionally good equipment and acoustics allowing the improvement to be heard, that is the cause of this perception.

If you read this, it was very interesting to hear about the way you set up a demonstration room and how you treated some acoustic issues, I was really eager to hear more from an experienced acoustician, thank you for this anyway.

[Hayabusa]

Thank you, Duke. Yes, when it comes to acoustics, there is so much more than frequency x amplitude. When you get the balance of these correct as well as phasing, reduction of comb filtering, reduced smearing, reduced multiple harmonics, and improved decay times along with linearity left to right and front to back, your spatial queues are more audible, overall resolution increases, and just more of everything on the recordings becomes audible.

I showed a prototype of a diffuser/absorber for use over a flatscreen TV. I immediately started receiving negative comments like “it’s a solution looking for problems”, and that TV reflections cannot be heard due to the angle and distance from speakers, and so on. So I instead of trying to explain to people that wouldn’t likely believe me anyway, I asked ChatGTP and posted it in the group. I posted it exactly without any editing. I was then banned from the group by the moderator claiming my response was offensive to members. Here below was the exact response I shared with them. I share it hear hoping people that read this will better understand acoustics.

ChatGPT, what happens to sound waves and reflections when a flatscreen TV is positioned between floor standing speakers on a wall or stand mounted, and would there be benefits to adding a diffuser/absorber panel over the TV like the one shown in the photos I took of the Ortvik piece and uploaded (uploaded these to ChatGPT)?

The following is a condensed simple version of what it said. I have the highly technical version too that includes mathematical formulas on comb filtering.


From ChatGPT



A large flat-screen TV between speakers acts like an acoustic mirror right in the most critical part of the soundstage. From a technical and factual standpoint, here’s what’s happening:



• Specular reflections (mirror-like reflections): The glass surface reflects mid and high frequencies almost perfectly back toward the listener, creating strong early reflections within a few milliseconds.

• Comb filtering: The reflected sound combines with the direct sound, causing peaks and nulls (typically 500 Hz–5 kHz), which leads to tonal coloration and loss of accuracy.

• Center image degradation: These reflections interfere with phase coherence between left and right channels, resulting in a diffuse, oversized, and unfocused phantom center.

• Temporal smearing: Early reflections blur transients and reduce clarity, making the system sound slower and less precise.

• Edge diffraction: The physical edges of the TV create additional secondary reflections, further degrading imaging and adding subtle harshness.

• Haas Effect: this is a critical element in perceived sound and spatial queues that is seriously affected by hard reflections in numerous negative ways.

View attachment 528199



The Haas effect (or precedence effect) is a psychoacoustic phenomenon where the brain perceives two identical sounds as a single sound if they arrive within 5–40 ms of each other, with the first sound determining the perceived direction. It is used in audio to create stereo width and in sound reinforcement to localize sound to a stage.



Now, placing a diffuser/absorber hybrid panel (like the one shown) over the TV addresses these issues very effectively:



• Breaks up reflections: The uneven surface scatters sound in multiple directions instead of reflecting it straight back, eliminating strong early reflections.

• Reduces comb filtering: By dispersing and weakening reflections, interference patterns are minimized, resulting in smoother frequency response.

• Improves imaging precision: With fewer coherent reflections, the center image becomes tighter, more focused, and more stable.

• Absorbs excess energy: The PET backing absorbs mid/high frequencies, lowering the overall reflection level and improving clarity.

• Enhances transient response: With less time-smearing, attacks are cleaner and decay is more natural.

• Maintains liveliness: Unlike pure absorption, this hybrid approach preserves some spatial energy, so the room still sounds open and natural rather than overly dead.



Bottom line: the TV introduces one of the most damaging reflection points in a high-end system, and covering it with a properly designed hybrid panel converts a major acoustic liability into a controlled, beneficial surface—resulting in sharper imaging, better tonal accuracy, and improved overall realism.

can you draw a picture of the position of tv and speakers and walls and the path of those reflections?
