Thanks for all the replies. I see all my options now. I will take the time to read through all the material. Until then, one thing I just thought of for a easy way to experiment with the 3 channel setup. I was thinking about trying to use 2 pre-amps and 2 power amps. First off, Ill split the output from the CD player. One signal into each of the (2) preamps. One of my preamps (Onkyo P304) has a stereo/mono switch. In mono mode, this LR output could be used to feed the Adcom GFA-555 in bridged mode a mono signal then to the center channel speaker. The other signal could be fed into the other pre-amp for normal 2 channel stereo. The only downside is that I will have a separate volume control for the center channel. But should give me a sample of what it will sound like. Ill post results once I give it a try. I think it should work?
