Used Amp Under $1000


Howdy y’all. After perusing this and USAM forums I’ve identified a handful of amps that seem pretty good. I’ll be using this amp with a McCormick TLC-1 Pre and Magnepan MG1’s. Please tell me your thoughts on which I should buy, why and what I might have overlooked.
Thanks!

DNA-1, hands down the best sounding amp on the list. Which I know having had one. And which you probably know, having the McCormack pre amp. Although to be honest I never heard the pre by itself, just assume the same sonic priorities come through. Which if they do, it is hard to find a better sound stage, or more natural detail free of grain and glare, and the ever elusive toe-tapping musicality or emotional appeal. The only solid state amp I heard that could give a good tube amp a run for its money. Which is the only reason I sold mine, not that the tube integrated I got was much better- it was, but by hair-splittingly small margins- but because it was an integrated, so saved me a pre, interconnect, power cord.

Not that the others are bad. Some on the list are pretty good. But not quite DNA good.
I’m not familiar with the Emerald Physics, but of the others, the CJ and McCormack are the most neutral, smooth yet detailed performers. Also,  they are hard to find, but I'd recommend a Muse One Hundred Sixty.  Excellent for the buck.
