Best used amp in the $1500 range

Odyssey Extreme, Possibly a mcintosh, but your gonna only find pretty old models at that cost.. McCormack is good, but is a toss up between it and the Odyssey depending on the system, another one I never heard but is in the range to outclass many from reviews would be a Belles 350 I believe, but not sure of the used cost.

Jack,

I've owned an ATI 1505 myself now for almost 9 years. Mated with NHT satellites and sub it creates a nice HT experience for me. However, it didn't float my boat for music and that's what put me on the path to 2 channel exploration.

I was going to say pretty much what Undertow said. McCormack DNA225, Belles 350A, Odyssey Extreme Monos will stretch the budget a bit but I think they'll all be a definite improvement over the Outlaw/ATI. Before pulling the trigger on an amp, read the forums more to see if that's the direction you want to follow. Audition if you can.

Good luck!

Nothing brings home weight and dynamics like a big class A amp. I've heard really powerful AB designs do it as well, but only at really high volume. Krell and Levinson come to mind, but not usually at that price point. You might find an older krell KSA-100 or similar Levinson since you are looking used, but be careful as class A amps might need to be recapped after as little as 10-15 years.

Perkadin, since you mention class A amps, I'm wondering if an older Plinius SA100 mkI or mkII might work well here.

I've never heard a Plinius amp so I can't comment, but I've found that in general, class A amps are able to convey the smallest details of a recording clearly and audibly without making your ears bleed when things get loud, and everyhing has such weight behind it. Each sound has a degree of physicality that makes the experience much more 3d and emmersive. They really work well for home theater and music. The downside of course is size, expense, heat... so they aren't for everyone.
