Best Amp for under 10K?

All of these are excellent recommendations. I want to include the Sim Audio Moon W5 amplifier to this list. It is a great amplifier and would cost half of what your considering spending. I am not sure if any of the suggested amplifiers are that much better than the Moon W5 in its ability to drive speakers with authority while not sounding hard. It is a very musical amplifier that will not make you concentrate on the low or high end of the musical presentation. It will make you concentrate on the music. Good Luck.

I would check out the new CAT JL2...supposedly phenomenal. After discount, you should be at 10k.

Other cheaper options:

BAT VK75SE
Cary V12 MK2

You can't go wrong with all 3.

I think the VTLs are ok, but they have so many tubes to replace....

I think Firebird is a loony bird. Rowland and Goldmund no good compared to awesome Krell, and Sound Factory second-rate speakers compared to all-time best KHARMA LOUDSPEAKER, supreme best. I hear designer Charles is a real nice guy too, he likes the picnics in the park. All-time best Lamm gooder choice too, Vladimir is total GENIUS, you know it.

The Moon W5 is a very nice amp. I owned one for about 4 months and sold late last year. IMO, my McCormack DNA-2 LAE is a better amp than the W5 though, especially in the lower bass regions. But they are certainly in the same league. I've not heard the Odyssey Stratos but IAR rated it one up from the W5 also and only costs $1000.

Berning ZH270($4500) or Siegfried($7500) OTLs.
