I'm trying to build a nice sounding system and so far I have speakers I really like, wired with Monster Z3(probley will sell and get either Z4 or M 2.4), the Monster Signiture Series voltage regulator and the Sig. Ser. 7000 surge protector is on order and the amp is the next thing I need to get. Sorry to ramble Jason
Well, first I'd reconsider what you are allocating for all of this Monster stuff and apply it towards your amp budget. You'll hear a bigger difference between amps than you will switching cable. Even Paul Seydor of TAS mentioned how absolutely miniscule the audible differences are between high cost/high profile cables and Home Depot outdoor power cord. YMMV.

OK, on to the amps. I've never heard ATI so we'll leave that one out in the parking lot. My impressions of the other amps you listed are:

Odyssey:
Pros-Very good for the $, will have no problem with your load, runs cool, decent if not stunning bass depth and slam, very good in the microdynamics, pick your faceplate, customer support before sale, enviable warranty
Cons-Silvery and sibilant in the top end, leans toward the cooler side of neutral, the epitome of ss sound and not tube like in the least (this could be a pro depending on your taste), customer support if you want to return it .

Parasound (This is the for the Halo, not HCA's):
Pros- Excellent for the $, smooth mids and top end extension, very good bass depth and response, neutral sound, cool looks
Cons- Can be a bit fuzzy sounding, not the fastest in transients, apparently a ground loop problem based on recent posts

Adcom:
Pros- Usually huge bang for your buck, slamming bass, good all-rounder
Cons- Can sound grainy on certain systems, sibilant highs, another amp that is damn proud to be a ss design and sounds like it.

Sunfire:
Pros-switchable current design, run cool, no prob driving your speaks, lightening fast transient response
Cons-Cold, clinical, analytical sound, not musical in the least. I'll be honest, I can't stand Sunfire amps so 'nuff said.

Of the ones you've mentioned, I'd pick the Halo in a New York minute. I'd then compare them to the two other amps that RGA and Psonic mentioned because they are absolutely right, both Bryston and Rotel and superb amps. I'm not a fan of Krell either but they are very good amps if you're into their sound. I'd also consider B&K and Aragon while you're out there. A'gon has some interesting options from Proceed, Classe, and I particularly like this one:

Hope this helps and good luck in your search.
