I have a combined system -- I use a Channel Islands passive preamp for 2-channel, and run the front channel outputs from my Lexicon DC-1 into the passive for HT listening. That way, no gain matching issues -- just turn the passive volume to max, and you're good to go.
That said, I WOULD have two systems if I had another room to spare . . . . sigh . . . .
