I recently replaced an old pair of DCM CX-27's with an old pair of Paradigm 9SE's. I have close to zero budget for audio so when i buy, i buy used.
The Paradigms have much better imaging - i'm always checking to make sure the center and rear's aren't on. They also have more dynamic range - but i'm still getting used to how much brighter they are, i actually turn the treble down a little on most material. I use them for 2-channel music, and as mains in a dedicated HT. The room has lots of carpet, upholstery, etc.
I power everything with a (used) H/K 335. Everything I've read about these paradigm's is that they sound better with more power... so is there a 2-channel amp (used) for around $100 - $150 that would signifcantly improve their sound over the current H/K? And perhaps someone could indicate how more power improves the sound..? I don't think I want it any brighter.
