Hi. I'm about to pull the trigger on an A85 with 7.1 board and have a quick question. I will need to buy another power amp for a 4.1 setup. If I get an amp that is bigger and better than the Arcams built in 85w amp, can I some assign or configure the Arcams amp to drive the rear speakers and use the external amp for the fronts? (Source is Denon 2200 Universal) I'm imagining I could run the Denons Front L&R to the Arcams Rear In and then connect the external amp(therefore front speakers) to the Arcams rear out. This should work for multichannel no? and cd? Thanks, B.
