Yamaha XDA-AMP5400RK Multi-Room Amplifier (4 Zone, 8 Channel)

This amp was incorrectly ordered instead of the MusicCast version. This amp was never powered on but was mounted in a rack for 3 days. Because the box was thrown away, I could not return to my distributor. They gave me permission to sell this for less than MSRP because it's technically "used". Here's your chance to either score a great amp at a great deal, or maybe you're just in desperate need of Yamaha product at the moment. Either way, I think the asking price is fair given the $1699 MSRP. Good luck! This won't last long!
Here's the official description:
