I Am original owner, smoke free, this unit is only a couple months old so you would have almost full warranty. I have original double box and everything that was included. The unit is still as new with no cosmetic damage. selling to fund another purchase.
The M50.2 is in NAD's Master series. The only component of it's kind to allow listening while ripping and choice of just playing a CD or ripping it. See the reviews, including Stereophile.
A couple tips, when streaming Tidal or similar the Ethernet connection is miles better than Wyfi and AES/BU is much better than coaxial. I also preferred ripping to FLAC which is the factory setting. An Ethernet bridge can be used if your router is not close by.
The 50.2 is ONLY a source with no DAC. You will need a separate DAC or have one built into your amp or receiver.
