Isn't that the trigger output (used to turn on/off another device - with trigger input, e.g. an amp - together with the M51)?

Hello all. I'm a recent M51 convert and just finished reading every comment in this thread. I chose to roll back to firmware version 1.39 and even reducing volume by 1 db to account for the fix did not mask the difference - it was clearly audible. So if you can, do.

And thanks to all for the education!

FW 1.39 is only possible for S/N before H25M51XXXXX accordig to NAD Support.

 

Cheers,

Tom

Fortunately that is not the case - I checked with them because my serial number is 33M51xxxx. They said it would be fine. It's more a matter of what firmware you are running. If you are at 1.43 or higher you may have to roll back through prior versions to get to 1.39.

In fact it seems to be the series with the older Zetex DDFA chip that can be downgraded. The newer production runs have a newer model DDFA that cannot use the older versions

Looking to jump into the m51 fray. Curious if current owners adjust the fixed volume settings according to the headphone you utilize. E.g HD800 vs LCD2.2F (the two i would use with it)...and if anyone has thoughts on synergy with a Luxman P1u or Bryston BHA-1?

Any feedback, as always, is appreciated.

Question:

No hdmi signal pass through if the unit in standby? 

 

post #1494 of 1524
Aside from the fact that there is only video pass-through on the M51, you are indeed correct in your assumption. When in standby there is no pass-through at all.

That and even when your m51 is on, but you have selected another source

I'm selling my NAD M51. PM me if you're interested in this fine DAC.

Same applies for the M12 + HDMI-1 MDC board (I just upgraded)

Hi , Yep there is interest. Well,.. you will have a definite buyer here.

It exactly suits my needs, HDMI inputs + co-ax+usb and  the colour matches my integrated valve hybrid amp.

I'm in South Africa, will pay shipping, prob about 140 USD.

Thanks

Neal

New NAD M51 addition to the mix this week.  This is an interesting DAC.  Definitely laid back, vocals sounds a bit soft.  Edges seem blunted/rounded.  Might take me some getting used to coming from the Benchmark:)
