Consonance Cyber 800/845 Valve amps; how good?

Bartok,
What are your experiences with the KT90 tube? Which amplifiers in what systems with what speakers? Or are you basing the decision on reviews and/or other posts?
Thanks in advance.

Bartok, your response is.................

Hi Audio, just on the one amp I own , the JOR. I've heard this amp through several speakers and had simuliar results, that is dynamic/detailed/fq separations. Not warm at all. Speakers heard the JOR through were Cabasse (MTM model 4 yrs ago), Mirage1's, B7W 602's, , Thors and Tyler LSS's. The Tyler was the cleanest image. This amp is colored only by the choice of speaker. There are few KT90 amps avaliable, I see Pacific Value is offering a new Ming da KT90 that looks of interest.
Peter, I do not think the 845 will deliver the dynamics in classical , at least not how I want to hear them. Like I say as a second system it'd bea great experience for some easy music and chamber classical.

I'm here late, but here's my $.03.

I have a pair of the Cyber 845s and I cannot say I've ever heard better amplification. It probably exists, but I've heard many tube amps up to nearly $10K, PP and SET, a lot of switching amps, and a lot of SS amps. What I haven't heard is SETs really up there in price (>$10K) or pricey class A solid-state amps.

The amps are dead quiet into my Hyperion 938s but more importantly just sound fantastic. Very extended, clear, pure, and transparent, with amazing soundstaging. Closest comparison for me would be the Art Audio Carissa I owned - more expensive, very similar sound, tho I do not think it had the same soundstaging abilities.

As for the parts - I can't speak to all of it but the caps in mine all say Rubycon. I don't think these are quite the best but they're very good, no? Resistors and wire - don't know.

The comment about the trannies is strange to me - they are not small by any means.

BTW I am using the CHEAP Chinese 845Bs and they are damn good.

i believe the internal wiring is by van den hul so may not necessarily need to be replaced straight away. its nice to get some kind of confirmation on these amps as like you i can't say i've heard any better. the differences are not subtle and to the point where i am questioning my own objectivity! i've heard a good number of the big american, english and euro name amps some of which had great merit but the cybers portray music in such a natural and quite sensuous way i stop thinking about the electronics. one of maybe two or three truly special components i've heard that have completely changed what i thought was possible (and were within the realms of affordability/sanity!) remember this is still a very young company. they should only get better
