I currently have Paradigm Studio 100s as my main speakers, with a Paradigm 450 as a center channel. I have JBL surrounds, and I'm driving everything with a Denon 3200. I'm hoping to see a huge difference by upgrading to the Parasound 2003 to drive the front 3 channels. Here are my questions (bear with a newbie, I have no experience with separates). 1. Do you think this is a worthwhile upgrade (e.g. I'll notice a big difference), and a good amp for my setup? 2. Does anyone know a good place to buy this and what would a fair price be? I'm thinking I may have get it at EBay or Audiogon. It looks like Parasound doesn't have a 3 channel amp in their current line ... 3. I hope this quest ion isn't too dumb ... but can I plug this into a standard wall outlet, or do I need some sort of upgraded power outlet? Also I have a Panamax 1000 surge protector, would that be able to get involved at all? Thanks a lot for any help!!
