This is a new unit I bought from an Authorized dealer (Amazon) 1 week ago to replace my Denon AVP-A1HDCI preamp which was giving me some problems.. I paid $3600. I have decided to get the Denon repaired, so I'm selling the Marantz at quite a loss. My loss is your gain. I'll pay shipping. If interested, my cell number is (214) 632-9003.
