Carver 275 Crimson tube amp --- any feedback appreciated

I've enjoyed tube amplifiers from Marantz, Dynaco, MFA, and Bob Carver as well as linear and switching solid state amplifiers in between. I experienced noticeable output tube degradation within one to three years as well as typical bias adjustments with all the tube amps except the Carvers.

I replaced one output tube due to my own clumsiness. The new tube measured very close to the rest of the original set that have been in service for the past five years. After the replacement the group bias was exactly the same. Case mounted tube sockets and point to point wiring.   
  
This review will give some historical background regarding the collaborative design and development.

Thanks for the insight, it is valuable.  I have had a ton of tube gear, including a HK Citation C-II and C-V, fully restored, and lots of other tube amps and I parted with them for solid state amplication.  I might revisit my affair with a tube amp with Carver's new offering.   It looks to be a robust and reliable unit at a very fair price.   

Hopefully, more reviews become more available. 

Liz,
I have pretty much abandoned tube amps for the obvious reasons, but am enthralled with with Don Sachs' 6SN7-based tube preamp... I think a lot of the magic of tube sound is captured in a preamp.  I went through a lot of KT88's, etc. with earlier tube amps-- a pricey proposition, and the biasing was a PITA.  Evidently the amp is not auto-biasing, but Carver's literature indicates that once you set the bias, it need not be re-biased for a long time.  

I am going to audition Don Sachs Kootenai KT88 amp soon so I will see if I can abide with a tube amp again.  I am rather dubious, but frankly have never heard a tube amp with more than 60 wpc and my Spatial Audio speakers, while rated at 94 db efficient (or is it sensitive?), did not at all perform well with my wonderful Dennis Had ~16 wpc SET amp.  It provided no "oomph" to the music.  It is somewhat similar with my Pass Labs F5 amp with 25 wpc of Class A power... it just doesn't have the same sonic presence as does my McCormack amp, not even close.

So, if the potent Crimson 275 amp will energize my speakers in the same way the McCormack does.... and

add more liquidity to the music

, then yeah, I am going to acquire one.  I am 65 years old and have had two boatloads of audio gear in my life, but I have never owned a Carver product.  Maybe now is the time...
