Thank you much, I'll be happy to know you impressions about M51.

Also I'm very-very interested how M51 differs from W4S Dac2 in sounding. I want to add some mood to a neutral HD800. 

Add a tube somewhere in the lineup.

I think about it. Maybe after new DAC I'll take another one tube amp.

Hi,
 
I purchased a M51 unit this saturday and yesterday after running some test I came to the Locking MacMini/HDMI input issue discussed before. I did not realize that this problem existed (before reading this thread) and I contacted the dealer. But as his dealership is stopping, he isn't responsible for the firmware upgrade now. What to do now to get the latest firmware?
 
Just mail the NAD support with this story and hopefully they provide the latest firmware (which I can sure upgrade, I'm a senior IT specialist)?
The M51 is a ex-demo unit...
 
Kind Regards,
Rens

As posted, NAD will give u the firmware to upgrade yourself. You'll be fine. How's it sound??

I'd already mailed them, so hopefully they help
 
It sounds like music!
I already tried various DAC's, but I like the somewhat warm sound of the NAD and its transparency. Its a bit upfront just like the DACs of my SSP300 of my Classe, but its just a bit more airy. The base is much more defined in a straight forward listening with my Airport Express on the optical 44.1 input in comparison with the Classe pre...
 
But then: USB in combintion with a straight out of the box MacMini as the source (iTunes)., It's like there's much more music to listen to. And what a beautiful soundstage.
Its just not like my old Mark Levinson 390S I used to have, which listens in layers. But it is closing in. I read some good things about programs/apps like Bitperfect and the much more expensive Pure Music for the MacMini... Today my wife is going to spend some money for an iTunes card to buy Bitperfect.
 
I'll let you know how that sounds!

its worth testing with the trial version of audivarna and a spdif converter if you can get your hands on one.

Hello, guys. I'm interested how M51 in pair with HD800 headphone? There is no too much brightness?

 
Nope, mine sounded pretty good from it.  M51 is recommended in my book.

Pulled the trigger on the M51 a week ago and haven't much looked back. 
 
Build quality is flawless, and it sits damn good on my desk with the new Schiit Mjolnir on top of it. All good, and designs match pretty good. 
 
My only issue was a popping sound on both channels for a while, but when I turned the volume on the dac down from 0 to -5 / -4, the issue resolved itself, fortunately. 
 
I'm currently using USB (I swapped from optical to check if the popping would stop), and in my head I sort of feel I get a bit less "sparkle" from the sound when using USB. Do mind, I haven't done any A/B-testing. I'm assuming I can swap inputs like a madman, and I'm going to check it out tomorrow testing both optical and USB. 
 
All in all I'm very VERY happy, and I can't see any reason to swap away from this DAC for centuries to come. Was it a tremendous upgrade from my Cambridge Dacmagic? Meeeeh ... I'm pretty sure I have a bigger sound stage, more impact and bass slam and more details, but you'd assume that from that huge price difference. All in all I'm very happy, and can really recommend this DAC. 
 
My five cents worth

Stop stealing my money!!!

I got my eyes set on this (M51) the Audio-gd 7.1 or the Calyx.
 
Are there any comparisons?

 

[MomijiTMO]

There are some Ref 7 and M51 comparisons on my local forum, Stereo.net.au and well they kept the Ref 7. The M51 wasn't as musical. That was it.

Someone else kept the M51 because it was more useful in their HT/stereo system. I get that.

 

[preproman]

How about the Calyx?
