Consonance Cyber 800/845 Valve amps; how good?


In my quest for a new valve power amp l came accross these;

Not much info around on these but their cheaper models are well respected. Look like amazing value for money, wonder if they have the sound to match?

Any owners or listeners on the Gon?

Tbg unfortunately i haven't heard the 211 valve as they aren't exactly thick on the ground in aust. very keen to do so nevertheless. there does seem to be a bit of effort to make really good new 845s (KR, SuperTNT 845M) and it bugs me to cough up large bucks just to re-tube which is why i'm tending toward the 845 as it means i can mess about with more tube-rolling! if you like horns (and have the room) the 300B can work fabulously.
Bartokfan (bit of a fan myself btw) you should really try to get a listen to the cyber 845 (or deHavilland/ Cary amps). i am going to arrange another more extensive audition of the cyber as it does seem a bit too good to be true. it has a very well balanced sound right across the spectrum with no obvious compression. definitely more warm than cold but in no way sickly sweet with excellent detail and upper air. it's all there but it just doesn't shout anything at you or draw attention to particular frequencies. you would never confuse it with a transistor amp. having said that i have separate transistor powered subs so the cybers were not doing a lot of work very low down. i'd love to have the 800s powering the subs and the 845s running the main speakers. now that would be fun
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.
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.
