I am looking for a multi-channel H/T amp. to drive my Rocket speakers. I will be using a Denon 3803. I have read info from others on the Marantz MM9000, but I can't get myself to believe that this amp is any good mainly due to its cheap cost? Why is this amp so cheap as compared to other with similar power etc. Is it worth purchasing? I really don't need anything more than 150 wpc, but my Rockets would love the 200 watt power! I've looked on audiogon and need something in the $800-$900 price range. Any input would be great.
