You are bidding on a perfect NAD t777 surround sound receiver.  This is a current model top of the line product.  I purchased it new about 1yr ago and can include the original receipt with purchase.  It's still in factory warranty.  Costs $3,000 new.   Comes with the box and all the original accessories, including manual and remote, audacity microphone, antenna 

Sounds incredible, unfortunately I'm selling my theater equipment as I do not have a place for it at my new house.  

This thing is near flawless.  Smoke free home.  This was kept in a dedicated av closet with proper ventilation before taken out old service.  

UPDATE:

I had several people contact me to ask if this included the 4K upgrade.  I called NAD, and the board was back ordered a week but they sent it right out to me.  See photo.  The 4K HDMI board is included.  I'm not going to install it, but it is included with the receiver as well as the original HDMI board.  

This is a top of the line 4K receiver with the new board included.
