Looking for suggestions on a used amp or new. $2000/ budget



Hello everyone, I've recently purchased a Emotiva  XMC-1 Pre Amp, Paradigm S6's and the matching center (C5 v.3). I currently own a Emotiva LPA-1 amp. After getting my system set up, I feel that the LPA-1 isn't giving me the feed back and detail I want and might be lacking in power.  So, that being said, I'm looking for suggestions on what amp would push these speakers and give me the sound quality I'm looking for. I'm a movie guy first and music second. But as I get older, I'm leaning more towards music.   I'm currently looking at an older Aragon 4004 or 8008. I've heard great things about these amps and I'm considering purchasing one or both. I'm open to all suggestions, used or new. Thanks in advance for your assistance.

I have used an Odyssey Audio HT3 for about 10 years. It is a 3 X 150 watt SS amplifier that works very well in my combo 2-channel / home theater system, powering the front three channels. The one word I would never use to describe this amp is bright. It is smooth, offers excellent extention, and a wonderful soundstage (for stereo). It is priced at $1650, but I would suggest the capacitor upgrade (which I got), for a few hundred extra. FWIW, I compared this, at the time, to amps from Rotel and Audio by Van Alstine, and the HT3 blew those amps out of the water.
Get the new Quad Elite QSP or QMP amps. They compete favourably with amps costing $20k+
Thanks everyone for the input.  I'm still on the fence as what to get.  I think I've come to the conclusion that I need to try a few so here's my list: 

Aragon 8008 
Parasound A31
Emotiva XPA Gen 3 
Anthem MCA 50 
 
I'm not fimilar with Tom Markers amp but I will do some research on them too!  

gdhal- you mention that you wouldn't mix and match components, is that really an issue? 


Definitely the Parasound A31 or A21, first.  Got several A21's and the JC1's and JC2 - all are superb with almost any speaker.

However... my close 2nd... and... maybe my first for the money... is the "ClassDAudio" SDS-470C at $700.  Regulated linear power supply, so no "class d" sound issues.  To me it sounds almost identical to the A21, and they have multi-channel amps also for very good prices.  Much lighter, cooler and cheaper.  I've had mine for 3+ years - it's been great!
