I will soon have in my posession the following power amps, a Rotel 1075 (5 channel), a 1066 (6 channel but only 60w) and an RB-03 (2x75 or something). I have a Denon 3803 for decoding and want to set up a 6.1 system with a centre back. Now, do I use the 1075 for the 5.0 speakers and use one of the amps in the 3803 for the centre back? Or, so I use the 1066 to biamp the fronts and centre front, the RB-03 for the surrounds and the Denon again doing the centre back. I must point out that music is my priority and wondered if anyone had any views on the above options. Will biamping with the 1066 be better than single amping with the 1075. Keep in mind that cash is tight so I either keep the 1075 or the 1066/RB-03 combo and sell the other.
