This is a B-stock marantz 6300 avr sent directly from Marantz America as a replacment for my previous unit. It was sent to me 4 months ago. This unit seems to work fine, but i just don't like the marantz sound especaily in my system. I have the original box/accesories/manuel/documentation. The condition is good except for a few scratches on the Surr mode knob. Since this was a bstock it was there when i got the unit. They are not noticable since you could just turn the knob and no one would see it. Who actualy would cycle the Surr modes using the knob when you could just press a button on the remote. I can send pic through email to anyone intersted. you can reach me at [email protected] and put MARANTZ6300 in the subject cause i get lots of junk mail. Price is $430 shipped.
