Check out the Anthem AVM20 Surround processor. Highly recommend this piece for it's sound quality and value. Depending
on your budget and space considerations, you might want to have a separate amplifier for your front right and left channels and then
get a 5 channel amp for the other five speakers. You'll get much
better stereo sound that way. But, if you have to have all 7 channels of amplification in one box, you're on the right track with
Lexicon. Anthem also makes a 7 channel amp, the PVA7. I have
not heard either the Lexicon or Anthem 7 channel amps, so I cannot comment on that. I have heard many surround processors,
though, and I cannot say enough about the Anthem AVM20.
