I have the Studio 100's V2 from Paradigm and really love the sound. Yet, I've heard from so many people that they really come alive with around 150-200W. I'm powering them now with a Yamaha ..85w per channel receiver. It's a nice entry level receiver RX-v795..but lacking in power. Do the Paradigm's REALLY change that much with a lot more power? My dealer tells me that better components like a high end receiver will do the same thing for the sound... My question is this... Should I Bi-Amp it (in that case what is a good high power amp..perhaps just 3 channel?) or, should I look into a good receiver like a Denon, or Onkyo etc. even though they might only have 110w per channel? I guess I have to think of the future, and seperates would be great some day. I don't know much about Amps right now. So my problem is that right now, I only need a two channel amp for music, and I can bi amp it with my Yamaha for movies to get the other 3.1 channels. However, if I go with a pre-amp someday, I'll want a 5 channel amp...AHhhhhh!!!!!!!
