I'm on the list for the TRL multi-channel pre-amp, a couple after the review unit going to David Robinson. I've had Tube Research Labs pre-amps since they first came out, nothing else comes close in dynamic range, bass, highs. I use to not take "surround sound" or multi-channel seriously, but have heard a few good things, some good DVD movies are okay, 'some' SACD engineers get it, all multi-channel media is not gimmicky and stupid. And I agree with gspdbeemer, that I don't want to lose my good 2 channel sound, I like listening to my old jazz analog tapes and jazz LP's.
I never thought I'd be saying this, but there is finally something to this "quad" thing. If you haven't heard a convincing demonstration of this, then it is either the gear, or the source material's engineer.
Two channel is probably where it's at for me, I'm use to it. But, for a very few, now, exceptions, I want to check out MCH.
