Just a couple of two-centers:
ComradeX, saying that two things go together "like oil and water" is saying they DON'T mix at all, just as oil and water don't mix.
MKtheater apparently believes 2 channel and theater do mix like oil and water. Unfortunately those of us who do listen to two channel (sometimes called "music") more often than home theater, and don't have as much money as some others apparently do, simply can't afford to hold such beliefs. Sorry about that.
