This unit came to us from a Marine Electronics installer that worked primarily on Yachts.  They were liquidating excess inventory and this one was of the pieces we acquired from them.  

This unit is New Old Inventory, Open Box.  It includes a AM/FM loop antenna, Power cable, Instruction manual, a Test Mic for making sure your stereo system is set up properly, and a remote.

These sell for over $500 from a big box store or local retailer.

From CNET:

“Marantz is still the original and best, and while little has changed in terms of power or performance, the NR1508 is the most feature-filled example yet. Alongside 4K HDR support on the HDMI ports, it’s also one of the first receivers to include Denon’s HEOS multi-room music system.
