I own an excellent Onkyo TX-DS 797 (a 6.1, 6*100W) which I enjoy very much, no clicking or dropouts so far.. I am looking to get new front L/R speakers for this receiver. I'd like speakers that provide excellent highs and midrange detailing and that doesn't require a lot of power to play loud. I listen to music 60-70% of the time and the rest is for Movies with this receiver. I'd prefer large speakers as I think they are better than small ones. I am looking at possibly Boston, Klipsh, Infinity or Polk Audio. My budget is $500-1000. (for the L/R and center if it has to match). Do I need to match Center speaker to the Front L/R? How about the surrounds? I have a Velodine sub, a CT-100 and it's fine for my needs so far. Any advice is greatly appreciated.
