$1000 to spend on an amp used

I don't know your speakers, or how much power they like, but I 2nd the advice as to C-J SS amps, or McCormack. Lots of used C-J SS amps, MF2300, 2250, etc. should be under $1K--just do some research on the various models. And McCormack--DNA .5, or 1.0 depending on how much power you need.

McCormack DNA amps for my choice under $1k.

I have a slight problem with this concept. A used 8/9 $$ amp only shines with a good front end and good speakers. I just don't think "this" 8/9 $$ amp, is going to elevate lesser quality items. I do think there are several 8/9 amps that will sing;along with good stuff, elsewhere in the chain.

Look for a Forte 1A or 4, about as good as a solid state gets under $3k. I have owned almost all of them including Pass X350 and McCormack DNA-2 Deluxe, Forte is as good or better.

You have lots of options, for sure. I tend to agree with Warnerwh in that your best bet may be to get a used Rotel power amp – like an RB-990, RB-1070, or RB-1080 for $400 to $600 – and spend the rest on a better CDP. Original Rega Planets go for around $350. Add those two pieces to your system and I think that you would be very pleased.

Good luck!
