You are most welcome, Bob. Even though you always hear the adage "garbage in, garbage out" - and it IS true - I have found the most profound differences are between different speakers. And, the speakers are the only element in the chain that DIRECTLY interact with the room.
Also, speakers are the only unit in the chain (except for cartridges, but we're talking digital here) that convert one form of energy to another. In the case of speakers, it's electrical to mechanical.
Having said all that, I would recommend you try to figure out what speakers you find most pleasing in your price range and go with those. Buy used, nothing wrong with a used pair of speakers providing the owner exercised reasonable care and feeding [smile]. I can give some recommendations, but you need to decide for yourself. All of these speakers will *kill* your current pair:
1) Paradigm Studio 40 or Studio 60 - these offer *excellent* bang for the buck. The 40s will require stands, the 60s are floorstanders. I prefer the real-wood V2s over the V3s.
2)Epos ELS-303 - There is a pair of these on Audiogon right now for $540. Very good speaker for a good price.
3) NHT 2.5 - I have a friend who has these, they punch well above their weight. There is a pair on Audiogon for $500 - that's a smokin' deal.
