NAD M10 V3 BluOS STREAMING AMPLIFIER

Are you also in the setting 'Source (detailed)' for this input?
Yes.

Can someone recreate this test for me with a NAD M10 V3?

I have music stutter when i enable "auto sens" on the "optical input" source when connected a live SPDIF cable.
It only happens when:
  • An live optical cable is connected in the optical input
  • Streaming on the NAD (Tidal,Spotify,...)
  • Turning on "auto sens" in the source "optical input"
So with the optical cable not connected or with auto sens off everything is working normal.
See this video, it will explain it all.

MOD EDIT- MEMBER CONFIRMED:

This problem was fixed by NAD support with an update.



Here you see it happen in the logs.

Yeah it is not working on the optical connection for me.
I'm surprised that M10 and M33 differ in this respect:

Last time I purchased a 2nd hand NAD M10 V2 in order to be the amp of excellence for my Sony oled TV in my living room. This Amp should drive my MMR compact 2 way speakers. So far so good. The price for the used NAD was good, 1500€ for a more ore less new device was ok for me.
Than, yesterday the package arrived and im trying to set up the system today. First test: what is that? Bad flaw sound, a lot of glitches, no dynamic, all together horrible. In other words not enjoyable and not to use. First thought was the hdmi cable from the TV eARCport is not ok. Changed to another and better one: no change. Not useable. What the hell is going on, was my thinking. Then next step: connecting the M10 via toslink to the amp: result was completely the same: A lot of horrible glitches, bad dynamics, all together not useable.
So what to do? I have searched in the web about this problem. No answers. Only recommendations for pcm output configurations for the hdmi eARC port of the tv. But this settings were already set.
To test the toslink connection in order to “Border in” the fault I connected the toslink to my Technics SC- C70 “Radio”. Result: perfect sound, no glitches, no problems. Switching back to the NAD: not useable, horrible sound as above mentioned.
Next step: connecting the M10 via analog input to my benchmark DAC1 and toslink from TV to the Benchmark DAC: a little better but also not good. The glitches a little less in comparison to hdmi input, dynamics bad, all together not that what I wanted. There must be an error in the NAD digital Device. After then I contacted the 2nd hand seller and told him the situation: he will immediately take back the NAD, payed me all the money back, additional postal costs for sending the package back. I was overwhelmed about this.
Under the line: I don’t know how the NAD should sound correctly. But in this situation there are worlds between in comparison with my Benchmark DAC1 and HiFiAkademi Poweramp V2. Really large worlds.

In that way, does anyone have experience with this problems and the NAD M10 V2?

Did you do a factory reset?
Yes, have forgotten to mention before, but factory reset did not change anything.
The amp is still not useable. Also disabling tone control and Dirac, same behavior.
Interesting are also the tone glitches between two tunes of YouTube music from the oled tv Never heard such awful glitches before on any device.
 
Have the newer versions fixed the CPU noise that Amir detected in the V1?
My V1 had the noise problem solved with a software update several years ago.
 
The problem is not noise. The problem are bad dynamics and a lot of glitches during change of dynamic volume. For example I’m using this tune for testing:
In the beginning horrible glitches after any bass note of the base player.
 
So how is it possible that you were able to deactivate Dirac Live after a factory reset? This should not appear in the menu at all. Something is wrong here.
 
In my opinion there must be an issue/ error in the DAC section of the NAD. And analog signals are first changed to digital data via ADC and then operated in the device…. So it seems possible that the device has a massive error.
 
If I have time I will give you a sound sample from the NAD and in comparison with the Benchmark DAC1 and Hifiakademie Power amp. Your thoughts would be very interesting for me.
 
Did you follow this procedure?

Force Factory Reset
Disconnect the mains power plug from the mains power outlet.
Press and hold rear panel Standby button and while doing so reconnect the mains power plug to the mains power outlet. Do not release the Standby button.
After about 30 seconds of holding down the Standby button, the NAD logo indicator blinks red.
Release the Standby button as soon as the NAD logo indicator blinks red and front panel display shows “Factory Reset...”.
Successful Factory Reset is indicated by the unit rebooting.

thanks for the information I will try this tomorrow again,
 
So, i have done the Factory Reste as describled above. But this makes no Change in the behavior. The Same glitches as before.
There must be definetely a defect in the digital path of the device.
Next step is: Sending back the device and then this adventure is finished.
 
I would like to share a short video about this problem, but as it seems to be not possible to upload videos to this forum.
Here i have uploaded the file to a filsharing-host. You can download the video and enjoy the perfect soundstage ;-) Fast recorded with my iPad without any special tuning or else.

Is it known what internal sample rate Dirac is running at on the M10 v3 yet?
(I believe the M33 was 24/192? I would assume the v3 will be the same but would be good to know for sure).

Also, is it known when Bass Control will be added yet? All I can see is buy the end of the year, but that has now passed.
 
Given that NAD promised over four years ago that the M33 would get a firmware update to add DLBC, I wouldn't hold your breath.
