Marantz Model 10 integrated amplifier

[evanft]

I look at products like this the same way I look at high end watches. They don't work any better than something much cheaper, but I don't care. Still cool.

 

[What?]

Yes and no: Marantz usually give only the continuous power and in the marketing material they state it over 8ohm. So they are leaving something like 6db of crest. It is still possible that, esp. at 2ohm, they are power supply limited.

Thks for this interesting reply.
Yes Galliardist it's for me a power amplifier. I feed him with a UD-701 preamp DAC phone amplifier TEAC. Great results as the UD-701 As the UD-701 has enough gain for the stereo part. Not so expensive by the way this UD-701 with great sound stereo and headphones (2500€ in France can read everything even via network even 32 bit float).

2x 375W @ 8Ω, 0.1% THD
2x 750W @ 4Ω, 0.1% THD
2x 1200W @ 2Ω, 0.1% THD
And the rate is at 0.1%.
Apparently the best is Purifi in module amplification then hypex and ice(a bit harsh). Do you agree?
By the way by MA we have apparently a serious

P801 Mono-Block Power Amplifier – March Audio

The P801 is March Audios new flagship mono block power amplifier. Based on the new Purifi 1ET9040BA module, this simply elegant product is milled from solid aluminium with a tough anodized treatment. Exceptional fit, finish and build quality. Class leading technical and subjective audio...

manufacturer. He uses for the 1et9040ba with no usual hypex Alan March Says:
the power supply is a new design that has 2 quadrant operation and active synchronous rectification. This means the output voltage stays much more stable and won’t suffer from bus pumping. The PSU can also output more than 1500 watts which means it will power the Purifi 9040 to its full 2 ohm load capability.
Other manufacturers still use the outdated Hypex supplies which will only drive the Purifi 9040 module to around 1100 watts short term.
Is AM right?

Apparently Bruno P. was impressed by the smaller amp https://marchaudio.com/product/p501-mono-block-power-amplifier/
After testing and auditioning the P501 Bruno Putzeys stated; “your input buffer is more transparent than our Eval1 board”.
And the speakers apparently surprises everyone:
Sointuva AWG Stand Mount Speaker (PAIR)
Ukkonen AWG Floor Standing Speaker (PAIR)
Both with The SB Acoustics Satori TW29BNWG Beryllium Dome Tweeter and Purifi PTT 6.5 and 8 Purifi drivers. Purifi drivers apparently are very capable due to their ability of long-stroke movements. I will have a look on the other feeds. Ap On the other feeds.parently this apparently this speakers offers a great sound for not so much money.

I do not agree that the Hypex PSUs are outdated. But clearly they cannot provide the 9040 the juice it needs, because the 3K, for instance, has 63V or 85V outputs and that's too much for the 9040. Since the 9040 is full bridge it should not cause bus pumping in the PSU, hence active synchronous rectification is not needed. But it is nice to have.

You're talking about the latest Hypex PSUs Ncore X or NILAI? I suppose they are great yes. I've heard the elder Hypex nCore module in AVM monoblocs the great German Hifi company. Very pleasant. Dynamic great controlled.
The remark about the sound superiority of the purifi modules cames from Audiophonics team. They compared all three latest modules purifi eingentakt hypex ncore X nilai and ice.

I was able to listen to the Model 10 today and it's finally a Marantz to my taste. The new Link 10n will probably get Dirac Live and other devices with Purifi are also being planned.

The Link 10n looks beautiful but for a $12K preamp with subwoofer out, I am surprised it doesn’t have XLR out for the sub.

I have not been able to find a better photo of the PCB, but these are probably the two SHARC DSPs:

You don't know that and neither do I. Nothing has been tested yet and I cannot locate an SM-1000 review to compare. Maybe you can?

Purchasers of the Model 10 won't really care about the internal amplifier "modules" in isolation, they care about the rated performance of the entire product- from input to output.

Marantz is selling an integrated amplifier here. "Integrated" means input selection, control, volume, preamplification, power amplification and output switching. A Purifi module is NOT that. It is merely a component. A bit like comparing the specs of a D/A chip with the advertised specs of the completed product.

The fact being Marantz themselves don't seem to know the difference when they advertise it as the most powerful highest performing amplifier they've ever made...

Their claim:
View attachment 390301

It may well turn out to be extremely powerful. It will no doubt exceed its rated specifications. But will it be the most powerful Marantz ever? Consider the SM-1000 ran +/-100V main rails and had 16 output devices per channel, twin 800VA transformers (1 for each channel) and 4 x 20,000UF 125V main caps. The Purfi can swing a maximum of 90V. The maximum module voltage is supposedly +/-48V. Do the maths on peak power and tell me which one wins- the SM-1000 by a mile. It all comes down to regulation and device losses. The Purifi wins on losses, but loses on available swing in the first place.

Purifi's own spec sheet says the 9040 will do 750W@4R@1% which is ~55VRMS (+/-77.8Vpk). It hits the wall hard at 400W@8R. Maybe throw a few more volts at it for the Marantz Model 10 SMPS, I dunno- maybe they did.

I don't have an SM-1000 (wish I did) but bear in mind it's conservatively rated at 400wpc@8R. Into 4R it will be close and the 9040 would win with 2R. The new Model 10 will likely outperform the SM-1000 example I used with inherent THD.

The internals reveal a bridged design, four coils, no visible power fets. Certainly not a discrete design, two dicsrete amplifiers per channel are more expensive than a symmetrical PSU. I would guess the TI based TPA3255 is inside, single chip bridged stereo. Like the WiiM Amp has.

Respectable specs in the data sheet. Without symmetrical power supply, good PCB design and EMC engineering are more critical. In a system that I built for friend (Arylic streamer and TPA3255 from ali), the TPA3255 amplifier just went defect. It was difficult to get it silent when idel. I stuffed in a separate PCM5122 DAC to get there, via IIS.

Oops, big mistake, I mixed up with Marantz M1, which has tpa3255. Not sure what happened here, was I too drunk, or too sober ;-)

Model 10 is different

 

[jpmomo]

I have been using the model 10 for the past few weeks in a small listening room with some unique components. It is even better looking in person and looks like it will last for a while

Went to listen to one today, was hooked to BW 803D4 and the new marantz streamer. Quite famieliar with the speakers as I run a pair of 804D4. I don't have much experience with thehigher end of D class amps, this was my first experience with such.To my ears it was very very clean, absolutely zero noise or audible distortion. But some reason it left me completely cold. its hard to explain but like the resolution was too high and it did not benefit the mixes of tracks I know so very well. There was too much separation between different elements to the point where it affected the flow of the music. As I said, its hard to explain but maybe someone can catch the drift. This is all personal experience and don't take my word for it. Probably way too good for my taste.
