You can bi-amp, but there won't be any advantage because it's using the same power supply.
Uhmm, i get your point..... ok, so better look for a stereo amp like BasX- A100, i guess...

Anyone notice any improvements on the BluOS update released 4 days ago? I'm hoping that weird loudness bug I keep experiencing finally goes away but didn't see anything specific in the version notes.
I have just tried to simulate the PCM volume bug and was able to replicate it "on purpose". I have hooked up my MacBook vial HDMI and started RoomEQ Wizard to send a PCM sine wave signal to the front right speaker. Volume was at -25 dB. Then I sent the same signal to the front left. It was as loud (- 25 dB). Things started to get messy after I sent the same signal to either the LFE or surround left/right speaker. Signal was much louder and stayed on that level even though the volume on the display did not change. Front left/right were boosted from -25 dB to -10 dB until I either switched to another Dirac slot or entered the OSD.
I have recorded a video and sent it to Jade (NAD). Maybe that helps.
Are you guys able to replicate the same behaviour? It only occurs with Dirac enabled!
Yes, that sounds exactly how I get the bug to come up. As soon as you send LFE to the receiver over HDMI from a laptop, it happens. I haven't noticed Dirac disabling, but believe you. I usually just power cycle the receiver and then it goes away, and it happens probably once every few months without connecting the laptop. Similarly, I only use the laptop for REW and configuring my MiniDSP so I rarely notice it anyways. Feel free to quote my posts as needed, I'm sure NAD will figure it out eventually.
@SimpleTheater: Are you also affected by this bug? The more we are, the better we can push NAD to find a solution!
I feel like I hit this like once or twice a week, and it finally forced me to get rid of it. No esoteric setup or anything, just Apple TV into the NAD which is connected to my LG.
I have my Apple TV set to output PCM, so I guess the AVR would get frequent switches between 2.0 and 7.1 depending on content, which seems to be what this thing can't handle.
Hi,
In theView attachment 88339 specification for NAD T758 v3 they are specifying that pre out THD+N at 2V is less than 0.006%.
How come you’r numbers show something entirely different?
Either you have something wrong in your measurements or NAD have, I suppose?
Can you tell us a little bit more of your measurment setup? Have you confronted NAD about these numbers?
Best regards,
Ok, I answer my own question. I suppose they have measured pre out using the analog inputs. And just ignored adding data for the DAC.
The Nad T758 V3 deactivates its internal amp of the channel when using pre out, this was told to me by a Nad employee, dunno how much truth is in this. Is this right?
Thanks.

With all the bad measurements posted in the review, will that be in effect when using it as a processor?
Thanks.
Base on the measurements, if you don't need more than 1 V output it should be reasonably good and if you need higher voltages it would likely degrade quite a bit, reaching 50 dB SINAD at close to 2 V. -52 dB THD+N is 0.2511%, likely audible.
