Carver 275 Crimson tube amp --- any feedback appreciated

I own the Carver Raven 350 amps and I'm very pleased.

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.
