audio.com.pl measured 44W/ch.
If mains are out of the equation. What could be? are you using two mono signals in two different acquistions and plotting them toghether or is it a stereo signal/acquisition? If the latter, then the poor crosstalk might be the culprit. Why not giving a run in mono to cross check? It might answer peng and others doubtsI don't think one is bad and the other good. Centrally located means it doesn't have as much variation reaching all the amp channels. It also seems to be under the digital circuits where it doesn't do any harm. Ultimately measurements show if there is a problem or not. Here, I don't see any mains frequency getting into audio path:

audio.com.pl measured 44W/ch.
My own guess: 97-98% of the owners/buyers of this receiver (X3500H) don't use them.
* I was looking @ the DACs measurements again, and of the NAD T758 AV receiver ...
scary! I hope Denon & NAD reps or better, engineers, are reading ASR. They have to be from China, Singapore, Malaysia, Korea, Vietnam, Tibet, Kathmandu, ...?
Mmmh. I am not sure I’d buy an AVR with good sound but just ok room correction. I think many home theater guys might agree with my preferenceYou can have a 9.2 system with a expensive AVR like the old and expensive Yamaha RX-V2700 (I had one). A friend bought it first. It has a very good preamp.

This amp allows ~83db of clean DR, are you aware of any recordings that require more than that or artists that consciously exploit a higher than that dynamic range?good music recordings with high DR like me
OKPure Direct.

Preamp.
Those of these AVRs that have preamp output only reach up to 1.2 Vrms (RCA). It is rarely documented.
I had few audio components over the years featuring Audyssey Room EQ (XT and XT32). I experimented extensively with all the various audio modes in both stereo and multichannel and analog and digital...Stereo, Direct, Pure Direct.
For my ears there was no contest...100% better in Stereo mode with Audyssey Room EQ engaged. And same for digital multichannel.
The other option I like was the analog multichannel...the 7.1-channel input, straight without any digital DSP and bass management from the receiver.
But the room EQ was better balanced overall digitally and bass managed...HDMI, coaxial digital, optical digital and analog stereo jacks (Stereo mode).
The Pure Direct mode I've never used, even with DSD.
To me when you have a decent room EQ like here, this is the main sound quality. Was it measured? No. Is it important? To me it is, big big big time. And I would bet that it is also for many many more. Measurements are super great, but when other parameters came into play (like here Audyssey MultEQ XT32), they take second seating. IMO, YMMV, ALLTHATJAZZ.
People who buy this receiver that's why they should buy it for among other features.
If you want strong quality power it has preouts (a feature of first order).
And, you can add the DAC of your choice to pass your signal through.
But most people buying this unit don't bother because they watch Dolby Atmos flicks from Blu-rays (1080p and 4K) and streaming. ...With Audyssey engaged. Measure that.
So, $600 is not a bad deal @ all, it's not easy to do better; because Dirac Live costs more, or unless you shop in the used refurb audio market and you can find one @ roughly half price ($300).
Black Friday is already here, there are many places with 50%+ off sales.
Who pay MSRP full price? Can you truly measure value from full price which the majority of people never pay? It's not realistic.
Here, in the $600 context it's more realistic.
Or go to the next level by spending $300 more ...

Modern AVR is a bad idea to listen to very good music recordings with high DR like me. At least with PureDirect, external DAC and loudspeakers do not measure badly but... It is true that the vast majority do not listen to high quality recording music and many even like MP3 sound more, so ...
The majority of the cheap improvements I had made is to reduce the noise, ripple and RF interferences and thus increase the SNR -> better sound.
I see. So the power amp section is contaminating the preamp DAC section by not being well separated individually and shielded from each other? ...Cheap implementation...you get what you pay for ... a bunch of neat features but forget it about audiophile stereo hi-fi digital music sound quality. Think Avengers: Endgame instead?
"With the AVR-X3600H configured to reroute the main front L/R internal amplifiers, the preamp is physically disconnected from the power amp. This allows the preamp stage full capability of delivering up to 4Vrms unclipped when connected to external amplification as can be seen in the following output vs distortion plot courtesy of Sound United Engineering.
Editorial Note about Front L/R Channels Preamp Disconnect
Front L/R channel preamp disconnect ONLY happens in a 11CH speaker configuration. If you have simply 9.1 channel configuration (5.1.4) or less, and you want to drive front L/R speakers out of external amplifier, or L/R/C, or L/R/C/SL/SR speakers out of external 5 channel amplifiers, internal amplifiers will not be disconnected. There is no selecting or sensing mechanism to allow that unless you activate 11.1 channel Amp Assign mode and select Front L and R for preouts."
"The SR8012 is capable of outputting 4.5Vrms unclipped from the multi-ch preamp outputs hich is more than 2X voltage drive needed to make most external amplifiers reach full unclipped power.
Editorial Note about Preamp Mode:At 1Vrms, the FFT of the SR8012 was good but I was surprised at the 3rd order harmonic byproduct that was about 3dB higher than I observed on the Denon AVR-X3300W prior but it was very low at .0018% THD. Still the noise floor (-140dB) of the SR8012 was exceptional as you can see in the FFT below, almost -20dB lower than I measured on the Denon AVR-X3300W."
I was unable to do a preamp frequency sweep exceeding 1.2Vrms as it tripped the protection circuits since the power amps were still engaged and exceeded full rated power (140 watt/ch, 8 ohms, Av = 29dB). Unfortunately, Marantz doesn't offer a preamp only mode to disconnect the power amp from the circuit if you're using only external amplification. This is something I'd like to see ALL receiver manufacturers offer that include preouts to avoid this very problem I noted. It would also be more energy efficient as well. We will be testing this on receivers going forward and lobbying the manufacturers to include a preamp mode if they already don't. Please note it's unlikely you will ever run into a problem driving external amplification as normal program material doesn't behave like continuous sinusoidal sweeps like what was used on my bench tests.
82 dBA is the minimum I would like. Better more near to 90 dB. SNR-A at 1 watt. I do not want / need more than 90 dB.

This may also be why Denon hasn't engineered the AVR for lower distortion, the assumption being that the AVR is primarily being used with MultEQ. Good chance slight variations in the user's mic positioning during the calibration process have more impact on how the sound changes than the distortion that is added by the DAC and power amp.
Really? Do you have an example? I would like to analyze it in Audacity.There's already a plethora of excellent content, including blu ray tracks, that can benefit from the full 24bits of resolution.
