Paradigm Monitor 7s

I use Monitor 7s in a surround system for movies. Monitor 5s for rear and CC-370. I originally tried the 7s in a 2 channel system. They sounded just okay considering their price. I think Entrope best describes them. If you do want Paradigms, I would look at the Reference series.

If a wanted to pair either speaker series with a receiver in the 500 dollar price range what would be the best fit?--Cheers

Before settling on the Paradigms, at the same price without moving into Paradigm Reference price territory, I'd look at fellow Canadian spkr mfr. PSB, especially the Image series. Even the $499/pr PSBs are smooth, balanced, and uncommonly linear in response.
