Bob Carver Corp Crimson 275 stereo tube power amplifier.

I bought one of these just released amps from Bob Carver Corp. it was delivered here last night. I installed the four Tungsol KT120 two JJ 12AT7 and a one JJ 12AX7 tube. I listened to a few tracks before hitting the hay, my first impressions are very positive. thanks ,William

    What's most interesting to me is that Bob Carver somehow developed a relatively high output tube power amp that doesn't burn its power tubes up. That's wizardry!

    Bob did some calculations and he figures that the KT120s operating in the Crimson 275 using his DC restorer circuit should last in excess of 40 years.

    Also, I am curious as to whether anyone else here ended up buying one of these amps when they were on sale late last year. If so, what are folks thinking of it/them?

    These are fantastic Amplifiers. I've heard it several different times with various preamps and speakers and have always found them to sound really nice. I will have one myself within the next month.

    If anybody is interested in one, I know that the introductory deal is over, but Jim Clark stereo in Rockford Illinois does offer trade-in allowances!

    cool, keep us posted on your experience with one in house.
    I am still kind of intrigued by these -- although not intrigued enough to invest in one*.

    Just found out that Jim at Jim Clark Stereo has a trade in unit available for $1950. He offers a full value trade in, trade-up for people who purchase the 275 if they decide to upgrade to the big 350 monoblocks. This unit is still under warranty and in perfect condition. It would be a great opportunity for someone interested in buying one of these amps.

    I've been running mine every day for a couple months now. I absolutely love it. I actually can't find anything I don't like about the sound of the amplifier.

    Yeah, that was the retail. I asked about this amp awhile back, seemed like it was all that when it came out and then crickets. You still using yours ? Any updates on the sound, any problems, tubes being used ? I really dig the looks of this amp.

    At 75 watts a side, what speakers are you using and do you feel this amp has enough balls for 4ohm floorstanders to be driven at decent volumes ?
