I was curious as to would it make any difference to upgrade my current denon 3802 w/ a denon POA 5200 (125x2 front channels) to the 3802 w/ a parasound 855 (85x5)? I am running 3 M&K 750s across the front (4ohm /88sens) and 2 m&k 550s (8ohm)in the back. My systems sounds fine as is however I probably can sell the 2 ch denon for the same price as a parasound 855 (seems like a good idea to eliminate the reciever amp all together, which I only use 3 ch. now). I hear alot how the 85 wpc on the parasound is very conservative, does any one have a actual test rating?
