Used Amp Under $1000

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 ! MrD.

It appears the particular DNA1, as you selected above, has been overhauled, so, imo, you are good to go. Odyssey, although excellent, is a very warm sounding amp, if you like that. The CJ as well. The particular Classe has less " balls ", or " oompf ". Not a tube fan, with maggies, and not a Class D fan, at least not those above. Too bad you cannot hear them all, as you are getting opinions, mine included, as to what each of us likes. But for me, the Vidar or the DNA 1. Enjoy ! MrD.

What about a YAMAHA MX1000u or any Sony ES.

overbuilt, massive power, quiet, bulletproof.

And yam has the 80’s synth style led VU meters. Sick!

Unfortunately, the Japanese use speaker switching, which limits current and adds some noise. Internally bypass the speaker switching, change out the speaker output jacks to better ones, and replace the stock power cord with a beefier, heavier gauge one, and you have taken the amp to another level in SQ. Any technician should be able to do this. If you think these amps sound good now ?

Mr decibel not sure what you mean.
