Just got my tax refund and am now ready to shop for a power multi-channel amplifier in the price range of $900-$1400... hopefully this will help take my home theater to the next level. Something new or a couple of years old would be great. Ones I have found are: Outlaw 755: 200x5 @ 4 ohm Rotel RMB-1075 (used): 200x5 @ 4 ohm Marantz MM9000: 150x5 @ 8 ohm Parasound HCA-1205A (used): 200x5 @ 4 ohm Sherbourn 5/1500A: ??? My current 5.1 setup is: Receiver: Yamaha HTR-5760 Fronts: Polk LSi-7 Center: Polk LSC Surrounds: Polk LSi-7 Sub: SVS PB1-ISD Do I really need a 5 channel amp or will a 2-3 channel be enough and let the receiver drives the rest of these 4 ohm speakers? What would be a good wattage on the amp for these speakers? I usually listen at -20 below reference level and it sounds good. Heard that I'm really not getting the most out of these speakers at the moment. What would be a good amp in the $900-$1400 to go with the HTR-5760 and these 4 ohm speakers? Thanks for any help I can get.
