Several listeners have reported that different firmware versions have an influence on the sound of the M51. General consensus seems to be that v1.39 is the best sounding with v1.41 having less bass and is not quite as dynamic. It would be interesting to know what version firmware the latest sample runs. As a long term user of a NAD M51 I find your further thoughts on this remarkable device very interesting.

Turning on the M51 with the Input button pressed reveals that our new sample is running the v.1.41 firmware. I have no idea how to roll it back to v.1.39 or if that is even possible.

Thanks John. It is easy to change firmware versions. V1.39 can be found here: http://www.fileswap.com/dl/BlRT7tfhYl/ . V1.41 can be found on NAD's web page. It would be very interesting to know your thoughts on any differences.
