I'm selling my Naim Audio NDX (with FM tuner module!). It is serial number 335xxx, so it has a late 2012 build date, although I bought it new in late 2014. It has the latest software (version 4.4), and is identical and every way to the most current version with one exception: it does not have bluetooth.
I bought it new and am the only owner. It was installed on a rack after purchased and never moved once. It is in perfect condition, rating 9/10 due to age. Firmware updated to 4.4 to bring it up to date with latest features (DSD, Tidal, Spotify). It has never had a single problem and works flawlessly.
Again, with the exception of bluetooth, this is identical in every way to the most current version. It has the USB update socket on the back, and supports 192/24 files, DSD, Spotify, and Tidal streaming.
Includes original AC cable, remote, link plug and original box. I am still looking for the original manual... so it may not come with that, but that is available online.
If you have any questions, send them my way!
