Hi Guys,
The Crimson 275 sounds almost exactly like the larger 350 watt mono-blocks. It has a strong and well controlled low end. Its detailed in the mids and highs but is smooth and never edgy. The soundstage detail is fantastic. It has nice tonal balance imho and the mid range is accurate. Female voices sound sweet but never overly thick, like in some of the vintage tube gear. It really has the best parts of tube audio without the high tube maintenance and heat output. I have sold them all over the world (Switzerland, Israel) with a 100% satisfaction guarantee. No-Restocking fee. They don’t come back. In stock. Free shipping in the USA.. Try it at home. If you don’t love it, just send it back. See my site w/ secure store or call.. |
I get a lot of feedback like this with Bob Carver products. I’ll start posting them. I have Email addresses if anyone would like to contact my customers direct. Happy customers are the best advertising. Christoph is a wonderful gentleman from Switzerland. In his own words. Unmodified. Hi JimThank you very much for sending me thewonderful Crimson 275. I had some time tolisten to my new music gear constellation.Here is a little feedback: (but please forgive my bad english)––––––––––The very nice made amp has a wonderful glitter paintwork,I think it’s signed by Bob Carver’s hand!? I like how it looks!First of all, the small size catches the eye.Even the weight is only about half of my old oneTube amplifier.But I do not fool about the weight! All that matters is the sound.To put the tubes into this amp is a children’s game!Plug in. Biascheck (was already accurate) – finished!No eternal screw with the multimeter.Let’s go, I’m curious!––––––––––First I listened to my all-time favoritesPink Floyd, Wish you were here, Shine on you Crazy Diamond.super detailed resolution: the sparkling stars at the beginning. Beautifully spatial.The transition and beginning “Welcome to the Machine” is almost scary.Wow.Bowie’s Space OddityIt almost makes me cry, goose bupms!Beatles, CAN, Silver Apples, Clapton, The Who, Hendrix, JoplinWhat should I say: I have never heard them any better.And I really listen to this kind of music since long time.Time to test some newer music:Flaming Lips “Free Radicals“OK, that blows you away! I hope that’s what my speakers endure Max Richter, Sleep, Dream 1: Hypnotic!Marc Robot is one of my favorite musiciansI have seen him about 10 times on stage.However, the sound has never been as accurate as in my sound room.Meldody Gardot, awesome! There sound worlds open.––––––––––Whether psychedelic, jazz, classical, pop, electronic.The transparent resolution, stage-image and the tonal spectrum is awesome!I was a little bit skeptical about this “listen to the room” function.My listening room is quite small.But the spatial representation is really much, much betterclearer and more spacious than with my old amplifier.The bass is very crisp, bone-dry and goes very deep.My old amp (Destiny Experience) was more of a roar in the room.The bass with the 275 does not hang in the corner.It’s somehow more physical present.The mids are very good and lively, I would say the amp has liquid, golden mids, very nice!The heights airy and precise but without the ears aching peak.––––––––––Size and weight apparently do not matter, when a genius head builds an amp!Small device – gigantic sound!It’s incredibly fun to enjoy the sound.There is such a vitality into musicI can fully recommend the Bob Carver Crimson 275!An amazing device I love it!Jim, I would like to thank you very much!And please greet Bob Carver and Frank Malitz from me.The Bob Carver Crimson 275 amplifier is awesome!Christoph

A question to Jim Clark. It is not clear how the biasing function on the Crimson unit works. I am guessing that one would not need a voltmeter for biasing, but it doesn't appear as though it has auto-biasing.
Can you explain the biasing procedure? Thanks.
The proceeder above is correct. Generally the bias is set close from when the amp was ran during burn in. After the amp warms up for a few minutes adjust as needed. Double check in 20 minutes. Personally I set them on 80 mA.. No meter is needed. The front panel meter read bias.
After this start up, you won't need to adjust bias again for years, unless you just want to experiment. The 350s use a similar circuit. I have ran those over 2 years, almost every day, without need to adjust bias.
Really about as painless as solid state. |
Thanks for the question. There is a single potentiometer on the back panel. It has a slot for a small standard screwdriver. You adjust it and read the meter on the front panel.. After that, it will repeat the same bias setting each time you use it for years. It could vary with incoming line voltage, but that is normally very minimal. Basically, set it and forget it. |
The Crimson 275 will be showing at Axpona near Chicago April 12-14 room 1215. This is the largest audio show in North America. See axpona.com. Bob Carver Corp and Jim Clark Stereo will be doing demos of the Crimson 350s, Crimson 275, Alchemy DDP-2 Preamp-DAC-Streamer, Wolf Audio Server and the Bob Carver ALS Loudspeaker System.
A new, shorter, prototype speaker from Bob Carver will be shown. During development, the new speaker system has picked up the nick name - Half Stack. Although still a prototype, it will be present and ready to sing for you.
We will be using the new Alchemy DDP-2 Preamp, DAC, Streamer. This Peter Madnick design is one you should hear. Even for those looking for more expensive products, at least hear the Alchemy DDP-2, and use it as a standard to judge others audio performance by. The DDP-2 isn't flashy or machined from solid aluminum, but the high end audio performance and outstanding value is all there.
It would be a pleasure to meet some of you and introduce you to the factory guys from Bob Carver Corp.. Jordon Gerber will be there. Jordon is a degreed Physicist. Jordon has been working beside Bob Carver for over a decade. Bob Carver holds a Phd in Physics and also a degree in engineering, although Bob never advertised his education (like Dr Bose).
Of course, you can always use our Satisfaction Guaranty and hear these products in your own home, anywhere in the mainland USA., without risk or restocking fees. Hope to meet you at Axpona.
Sincerely,
Jim

Thanks Frank. Looking forward to Axpona this weekend my friend. Stop and meet Frank in room 1215. He's been in the Hi Fi business since 1969. He has lots of stories about the product designs and launches of many of our favorite vintage brands and models. He's never at a loss for words and is fun to be around. Frank has seen all the industry changes and has interesting perspectives.
Jordon Gerber will be there. He can answer any technical questions absolutely, down to the physics level. Looking forward to meeting some forum members! |
