I had a conversation...OK, an argument w/someone today. Anyway, here's the scenario. You can't afford outboard power amps for all five channels, so you purchase a single two channel amp and power your main front (L/R) with it. The idea is that you have more power for two-channel stereo listening. The receiver still powers the Center and Surrounds. I say that you'll have problems getting levels to match b/c under transients, the outboard amp will provide much more kick than the receiver will to the other three speakers.I also say that the outboard amp will color the sound...not necessarily in a bad way, but the front L/R will sound different than the other three. He says that's totally incorrect. As long as the power amp is "a good one" you wouldn't hear any difference. And once you "match" the levels on all the channels, it's matched. Who is correct?
