I've uploaded the 1.39 firmware and installation instructions PDF here

$1k USD brand new?! Holy cow! Wish I could justify buying a second.
No experience with the Maverick D2. But for me, it was a slightly noticible upgrade from the dac built in to the McIntosh MHA-100 amp, and a dramatic upgrade from a Cambridge Audio DacMagic Plus.
I used the latter for sound from tv and dvr; usually those singing competitions, or performances on late night tv. I have this one recording of the 2nd performance of the 1976's on SNL. A really fantastic recording and mix of a very energetic performance. Once I switched to using HDMI to feed my M51, I was floored by how much better it sounded. How musical, yet precise everything was, with every instrument having separation from every other one, vs. the 'blend' the DacMagic Plus was giving me.
The up sampling tech used is quite unique, and not outdated IMO. And music from dual HDMI in is another feather in its cap to 'future proof it. I'm using both. At $1k new, I can't recommend it enough.
Just picked up a M51 and it has firmware v1.41 installed. I have copies of the 1.39 and 1.50 firmware. Can someone please send me the 1.41 firmware so I can flash my unit back to this version after testing 1.39 and 1.50? TIA
BTW, this replaced an Arcam irDAC. I've only listened for about an hour but the M51 is smoother in the high end, and more dynamic in the low end. I paid $650 for the DAC and am happy with the purchase overall. Thanks to all on this thread who have posted their experiences with the unit.
NAD M51 --> Doge 8 (4x Genalex 12AT7) --> Van Alstine 350EXR (2x Sylvania 12AT7WA) --> PMC OB1
Like most of the posts in this thread, I too would like to try the latest version of the firmware (1.50) to see first hand whether or not it sounds better on my system.
But I’d prefer to know that I can revert back to version 1.39 just in case. The support staff at NAD would not provide a copy of the 1.39 firmware. They said they don’t keep older versions once new firmware is available... Seriously!?
My M51 is currently using version 1.39 and there doesn’t seem to be any way of making a backup of it before I update to 1.50.
Can anyone please provide me with 1.39, and possibly the other versions as well?
Thanks in advance,
Derek
Did there has any new firmware later than v1.5? Thank you.
Hi!
having had the M51 for a number of years, i just stumbled into an issue together with my Mac Mini (macmini6,2 late 2012). latest Mac os X. The mac reports the NAD draws to much power via the USB, and then shuts the USB down (other USB seems to be working fine, can charge my Iphone X, read usb thumbnails etc). ive done the SMC reset that is recommended when USB fails, it worked once and the NAD was up again, but a few hours same issue and havent been able to resolve it since. i have been using the M51 together with the Mac mini all the time, i did replace the USB cable from Wireworld 7 to the Silver one, tried the old USB cable, no difference.
Connected it also to my sony vaio laptop and an error came up for a second about drawing to much power, but everything worked. and connecting it once again there was no message.
anyone had USB issues like these with the NAD M51? any suggestions?
