Peeking inside a Carver Crimson 275 Tube Amplifier
So, I just had to pop the hood on the Carver Crimson 275 tube amplifier. I was so curious as to how this little guy weighs so little and sounds so lovely.
Does the sound quality of this amp bear a relationship to the fact that there’s not too much going on in the unit? There are very few caps--from what this humble hobbyist can tell--in the signal chain. And, none of these caps are even what many would consider decent quality--i.e. they aren’t WIMA level, just generic. This amplifier beat out a PrimaLuna Dialogue HP (in my room/to my ears...much love for what PrimaLuna does). When I explored the innards of the PrimaLuna, it was cramped, busy and had so much going on--a way more complicated design.
Is it possible that Bob Carver, who many regard as a wily electronics expert, is able to truly tweak the sound by adding a resistor here or there, etc.? Surely all designers are doing this, but is he just really adroit at this? I wonder this because while some parts quality is very good to excellent, I was shocked to see the Suntan caps. They might be cheaper than some of the Dale resistors in the unit. I should note that Carver reportedly designed this amp and others similar with Tim de Paravicini--no slouch indeed!
I have described the sound of this amp as delicious. It’s that musical and good. But, as our esteemed member jjss [ @jjss ] pointed out in his review, he wondered if the sound quality could be improved further still. He detected a tiny amount of sheen here and there [I cannot recall his exact words.] even though he loved it like I do.
I may extract the two .22uF caps that look to be dealing with signal related to the 12at7 gain tubes and do a quick listening test.
- The layout is simple and clean looking. Unlike the larger monoblocks (that cost $10k), this model uses a PCB.
- The DC restorer circuit is nicely off to one side and out of the way. It doesn’t look all that complicated but I’m no electrical engineer. Why don’t more designers use this feature? It allows the power tubes to idle around 9.75w. Amazingly efficient.
- The amp has very good planned out ventilation and spacing. No parts are on top of each other.
- Most of the parts quality is good. There’s a host of Dale resistors, what look like Takmans, nice RCA jacks, heavy teflon hookup wire, and so on.
- Some of the parts quality is questionable. There’s some cheap Suntan (Hong Kong mfr.) film caps coupled to the power tubes and some no name caps linked to the gain signal tubes. I was not happy to see those, but I very much understand building stuff to a price point.

The 30 days appears to no longer be a limiting factor: https://carverstereoforum.com/forums/topic/bob-carvers-response-to-275-forum-controversy/ | ||||||||||||||||||||||||||||||||||||||
so what’s it to you? all 15 posts to your credit... below is the sum total of ALL your contributions to this forum so do you own the amp? do you feel better now -- stopping by, leaving your turd here? are you lookin’ out for all the rest of us, with your righteous indignation? --------------------------------------------------------------------------------------------------------------------- funky54Responses from funky54

@jjss49 I’m pretty angry about it. I’ve owned Carver made gear in the past. I’m angry because I really admired his designs. I “believed” in him. I defended him in conversations about his career and products. It bothers me because I’ve looked him in the eye and heard his tales. I’m not rich, I make sacrifices to own the gear I do have. I try to study, read reviews and know what I’m buying. I “almost” bought the 275 and was intending to still buy one possibly two, in the near future. I sat on a little kitty of money and was watching like a Hawk to buy used when this crap hit the fan. I’m angry. I feel foolish and lied to because I trusted what he said and what is advertised as their specs. I expect legitimate professional companies to be honest about measurements… even if they put their best foot forward and measure from the best possible perspective.. you still expect it to be in the range of what they advertise. This was blatant lies. The soul motivation is greed and at the cost of your client/customer. I have every right to be angry. Every right to say it.
I’ve owned: Phase Linear 400 Carver Cube Two Carver C-500’s verticly bi-amped. You don’t like my opinion. You’ve gone to great length to copy every word… cool I’m glad my posts were informative To comment on my limited posts.. I’ve checked Audiogon at least monthly for over ten years. I’ve bought items I’ve read about from this forum. I’ve learned a great deal reading all of your posts. I just was never moved to contribute anything until this thread. This truly deeply disgusts me. It eats at my passion for this hobby. I contribute and am far more involved in other forums. Not because I dislike Audiogon… but frankly, because much of the gear and reviews are at a price point I rarely can be involved in. I’m a lower tear in gear. Products like Rogue, Jolida, Roksan, Bryston, Spacial Audio, Alon, Monitor Audio.. I don’t often play in the Krell, Wilson, McIntosh world. Being “around” the industry I have had the opportunity to listen to and compare many high end brands.. but not to own them. So dislike me if you wish, we’d probably like each other if we met face to face and started to talk about how much we each love music and audio.
I wont post anymore, no point in it. |
