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!

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.

Why not try a new Schiit Vidar at $699 it will drive them no problems at 200w into 4ohms, which the Maggies are, and may sound better than the ones you mentioned, and you can trial it for 15 days.

I second the Vidar.  Used one while my Sunfire was being rebuilt to power my 3.5s.  Sounded great, but wished for more power, but I am in a large room, like to turn it up, and was pushing larger speakers than the MG1.  
I have not heard the Vidar, but it is getting a lot of positive press. It is also new, with a trial period. I love trial periods. I have owned a few McCormacks, as I am a fan of Steve's work. In my experience, however, amplifiers of his, 20 years and older, normally require rebuilds, which takes money. This is just my take on it, but obviously, others here disagree, which is ok. Enjoy !
