I have the Onkyo SR600 Receiver matched with Paradims, Mains are Monitor 7's. Great for movies, but I would like a warmer, richer, more open sound for music which is 75% of my listening. Should I change or is this as good as it gets at this price range? I could change speakers or Receiver or both. If you relate to the kind of sound I am looking for I would like to hear suggestions/experience. Thanks.
