Best 2 ch. Amp, for music, under $1k used


My current system consists of:
Classe ssp 25 pre-amp
Musical fidelity v-dac2 with Pangea p-100
Adcom gfa 545
Denon DVD 2900 used to play cd's
Paradigm studio 10 (planned future upgrade to studio 20's)

My question is: what amp would you recommend for my setup? I'm looking for better sound (fuller bass, better imaging, more power for higher volumes and more headroom etc). I'd like to keep it around $1,000, new or used.
By the way, there is a lexicon nt-312 for sale locally for $850. This amp is supposed to be the same as a Bryston 5b-st. Any input is greatly appreciated!

I have owned several McCormack amps and I would suggest you look at the DNA 125. Very musical, neutral and quick on its feet with great bass slam. The DNA 125 will work great with upgraded Paradigms as well.
I agree with the McCormack suggestions. I would also add the DNA-1, which is very upgradeable.

You might also consider a Monarchy SE-100, Marsh A400, or Musical Fidelity A3cr. A friend of mine had Studio 20'a and he drove them well with a Denon integrated amp.

You guys (and gals, if any of you are ladies) ROCK! Thank you all. I've researched some of these amps based on your recommendations and I've really liked what I've seen so far. The knowledge you guys have about stereo equipment is humbling. I'll definitely write down all these amps, do a little research and then start looking in a week or two when the funds are available. Thanks again to everyone helping me out with this, I really appreciate it!
