NAD M2

One owner - bought in 2011. This is a replacement unit for a refurbished unit I originally bought from SpearIt Sound. The original had issues, so NAD in Canada sent me this one instead. Not sure if this was also a refurbished unit - there is really no way for me to tell. It has been working flawlessly for all these years and I have now replaced it with a PassLabs amplifier. Rated 8/10 to be conservative, but it really looks like it did when it was new.   I will pay for PayPal fee and shipping in continental US up to $150. UPS or FedEx, whichever cost less.
