And BTW:  The PDF for the M51 states:

 

While the M51 includes the industry standard SPDIF inputs, including AES/EBU, Optical and Coaxial. The M51 also includes the latest USB technology fully supporting 192kHz sample rates, allowing direct connection of a PC or Mac. HDMI provides an encrypted HD Audio connection in PCM’s native I2S format up to 24 bit 192kHz.

I know you can't use a regular HDMI cable with the OR5 to the PWD mkII.  Maybe the HDMI cable from PS audio will work.  Who knows?

HDMI gives me troubles through the laptop and is noisy from ground issues compared to USB.

When the NAD was in my main rig I only used HDMI out from my macmini directly to my Onkyo surround sound (more mid fi system) for watching movies, HBO GO, and other internet offerings, and listened to some music. However, when I wanted to really listen to music, I used USB to NAD and my headphone set up. For a while I tried to use the HDMI in and then out to my Onkyo (so that everything run through HDM) but when the signal got to my TV (from my Onkyo) it was flashing. Maybe if i run the HDMI out directly to my TV that issue would not have been there, but I never tired. It was probably to many chain links that degraded the signal. Sound from HDMI in my system was not better than USB. I was not sure of that for a while, but after some repeated critical comparisons, that was my verdict. I never heard it nosier though, but that could depend on lots of factors that differentiate our systems.

Here's a thought.  Get the pin out of the PS Audio HDMI cable and ask Blue Jean Cables if he can make it..

NAD never said that.

HDMI on m51 receives the SAME spdif signal as the one that goes over it's coax.

the difference is only in the cables used.
