Suggestions for power amps

The Benchmark ABH is an excellent amplifier; I used it with my Fyne Audio F-702 speakers and got wonderful sound.  I sought a bit more power, however, and am now using two mono bloc Odyssey Kismet power amplifiers, which put out about 200 watts each, and the sound is wonderful.  Excellent imaging, great tonal qualities for the instruments, and dead silent background.

@mike4597 You could have bought another Benchmark and ran them in monoblock mode and that would have given you over 300 watts per channel.

In your price range, the Kinki Studio monoblock amps at $3700 have enormous power and recommended in a review as comparable to low $10Ks amps.  Todd at Tekaudiospecialties.com is the U.S. distributor, does modifications to make them even better and is a very knowledgeable audio electrical engineer (many decades of computer work).  I just purchased a SOTA CD transport from him (Jay's Audio cdt3 Mk3).  I'm looking to purchase a 10X more expensive amp (Westminster Labs REI monoblocks).  For the price, it could be what you are looking for.  

Audio Research VT 60 or Bryston 3 or 4b SST2. Marantz 8b if u can find a good one. Depends how many watts u looking for.

in your price range,  for the diversity of music you suggest and the qualities you are looking for check out the Odyssey amps.   Klaus is a master and a wizard with these amps and the value is way beyond their price tag.
