This unit is far too complex for me to describe it in detail, but I'm sure if you're looking at this model, you already know it was one of Denon's flagships. It's a robust unit that is incredibly heavy and is built like a tank. It was a gift from a friend for my home music studio. It was lightly used to power a couple studio monitors and it did that very well.
I have both the remotes for it, but have not personally needed to control the unit with a remote, so none of the remote functionality has been tested by me. I have no reason to believe something is wrong with the remotes, but just wanted to offer full disclosure on their condition, and condition of the amplifier. I've only used speaker channels 1 & 2 to power a pair of studio monitors at low levels.
DM-A505Z Audyssey sound calibration mic is also included. Receiver will be professionally packaged to ensure safe transit to its new owner. Cosmetically it's an 8 out of 10.
