Can anyone update me on the following:

1. Is it possible to integrate the M51 as a preamp in a multi-channel home theatre system? I like the DAC very much but without any analogue in I cannot figure out a way to integrate it, the HDMI in I understand is for stereo only.

2. Will NAD ever consider adding DSD over HDMI capability to it, or is it a done deal dead end?

Thanks.

Did anybody compare the NAD M51 with the T+A DAC 8? Both have favorite reviews but I don't see many posts on the T+A. Thanks!

Very interested in this new technology. I'm keeping an eye on the NAD C390DD, an integrated digital amp described as a DAC with a 150watt output, but first more reviews and some more time for the manufacturer to iron out the mistakes that are always in complex new products.
Price of this technology will probably go down too, I think this is the future of amps.

I agree. In fact, I ordered the DD390 yesterday. Very interested to give it a try in my system.

Thank's for a file. You haven't a changelog? 

 

[Somnambulist]

Cheers for that.

Hold left button when powering up, load hex file onto usb and insert into upgrade usb slot, from off position hold down left button below nad sign and switch m51 on,when u see bootloader message release button and wait for m51 to go to standby,then do a factory reset and thats you,ive sent file with instructions to you Gordik and will help anyone who needs update just drop me an email

 
I read this as:
1) Turn M51 off
2) Place USB stick w/hex file on into USB update slot
3) Turn on M51 holding down left button on front of display
4) When bootloader message pops up, release button and wait for M51 to go into standby
5) Perform a factory reset (I take it USB can be removed at any time after this)

Many thanks for this, and to Somnambulist for the instructions. I've now installed this update and my Mini-based server works beautifully! There also seems to be slightly less bass bloom but I'm guessing that's a warmup thing and not an artifact of the update.
 
best,
