    The 275 is their money maker... the Raven/Crimson amps are the real deal, and truly great amps. I always felt the 275 was a shifty-Malitz deal with Bob’s name attached.

    It does increasingly seem that way in terms of the 275.

    Certainly hope that you've cleaned the bottom of your shoes coming back out from the sewer of that so-called science site Mr. Hardy. You should look around some time and find out how totally clueless that egomaniac is. There are long, long threads documenting all his complete utter foolishness and incompetence.

That’s why I don’t, I bought all of my current gear based on technical parameters alone, such as specs and measurements."

    I am a member at ASR and spend a fair amount of time there.
    I am very well aware of the history Amir has, and I was extremely anti-ASR for a long time (do a web search & see!).
    That said, it is a very active website. there's chatter there about many, many reasonably priced products -- and there are some smart and savvy folks participating there as forum members (a number of whom do this stuff for a living).

    What I like about ASR is the level of activity on the forums there... the "old" sites are all more or less moribund, and I have no interest in social media "groups" for hifi or anything else, for that matter. :|

    This whole Carver Crimson 275 kerfuffle started at another forum, with another amplifier pro -- it didn't really fit at that forum and so the topic migrated to a more measurement friendly place. Simple as that.

    The bottom line about the amp in question is power output -- which is rather different than claimed by the manufacturer. Anyone with an oscilloscope, audio generator and a modicum of understanding could quantify that.

    I almost bought one of these amps -- I am glad I didn't. I have no doubt that it sounds fine in the real world... but I don't need another 15 wpc stereo vacuum tube amplifier; plenty good examples of those here already.

    I could've used a 75 wpc stereo amp (like a Mac MC-275), e.g., for the R200s.

    One thing I learned from all of this: The goofily named Rogue Audio Titan Atlas Magnum stereo power amp looks like it was a heck of a good buy.

    Have they actually posted measurements of the factory unit? I waded through 31 pages of banter but never seemed to find it

    Actually, measured performance notwithstanding -- what may be the worst thing about the amplifier's design & execution, from a practical standpoint, for a factory-built commecial product, is the use of a three-conductor IEC power jack... but with no chassis ground installed to the ground connector.

    cropped and tweaked to show the unconnected ground on the IEC.

    The product's not UL listed, so it's not required to have the safety ground, but it's, at best, really odd to use a three-conductor power jack and not use the ground. There are two-conductor "IEC-style" power connectors that could have been used instead. Alternatively, they could have used a hard-wired (two conductor, polarized) power cord.

    On the other hand, one less opportunity for ground loops.

    Ahhh I didn't know there was a separate thread made. Gotta read through that now

    It's gettin' a little ugly over there in after-the-fact banter, but, by all means, look at the data.

    The amplifier definitely wasn't very happy being tested as a Class AB audio power amplifier -- of course, that doesn't make it a priori a bad amplifier for audio use in the real world, but it does make it rather hard to verify published performance claims for it.

    It would be nice if someone like Stereophile's John Atkinson would put one on his AudioPrecision analyzer and see what happens.
    That, sadly's, probably not in the cards -- so all of this will likely end up being, as Shakespeare put it,
    a great sound and fury, signifying nothing. :|

    That was an interesting read, I didn't make it through all of the comments but interesting nonetheless.

    I do agree with a few over there that it would be a big disappointment if Bob truly has his name on them, that is what needs to be known, there is no way he doesn't know about this all happening, I am sure it has made it's way to him by now..

    I knew the pressure got to Jim Clark when he gave paulbottlehead a new name.

    That caught me off-guard.

    I'm almost certain that the Federal Trade Commission has received at least one call/email/snail mail about this matter.

    Unfortunately, it is Bob's name on the label and his reputation that is getting torched.

    That whole thread was exhausting to read. I am all about civil discourse when a product doesn't live up to the hype but man.

    Usually, when a product is submitted to be reviewed and it doesn't meet the specifications, the reviewer contacts the manufacturer and either another sample is sent or the original is brought back and figured out what happened. I just read a very long couple of articles in Audio magazine about how Sony sent three people to Audio's office and cooperated in a joint effort to see why the TC-355 didn't meet one specification although it aced every other one they measured. Sony ended up changing their final stage calibration process and offered to recalibrate anyone's deck in the field at no charge. Everybody benefited.

    You know, I may be off base, but from the measurements and parts quality /construction... It looks like a 100 dollar Amp in a fancy chassis

    Judging Jim Clark based on the way he handled himself in that thread, one can easily assume that if someone addresses short-comings of this product with him, he would saturate the conversation with plausible deniability.

    Although one can assume that Bob no longer has anything to do with the designing, manufacturing, sales, and/or servicing of this specific amplifier, if he was remunerated during any year the amplifier was made (assembled)/sold, and/or serviced, Bob was/is (unfortunately) involved and culpable. The sooner the company gets a handle on the matter, the better.

    It is my understanding that Bob designed it, and got paid, then left the partnership. There were several follow-on products that were coming, but are now not happening. As far as the company goes, my impression is that the drain in being circled and the plug will soon be pulled.

    That there is the funniest thing I’ve read this month. Can one even IMAGINE a dispute going to the FTC regarding published specifications on an audio product? Oh, the horror!

    I doubt he is totally out of the loop on this, no way is his name being drugged through the mud, and he doesn’t know about it..

    I am sure he knows... just don't think he cares enough to get involved any more. I am certain Matt knows what has happened with his name on the box of countless soundbars, but he isn't worrying about that either.

    All one has to do is actually talk to or listen Frank to completely understand. After listening to him at Axpona for about 20min. with him slamming Bob from every angle you would understand COMPLETELY!!
    I had to get up and leave it was embarrassing !! Frank actually said Bob was a nobody and couldn't design anything with out him. I LOL and said a few words of wisdom as I left the room. I wasn't the only one who walked out. Utterly a HUGE narcissistic EGO that with out Frank there would be no audio world he single handedly built all audio companies.

    I didn't go to his room, but I saw him walking past where I was sitting in the hotel lobby at Axpona after show close one evening. He was obviously drunk and having a loud conversation with someone else. I think he may have been talking about how great he is and how his **** don't stink.

    The tone of his voice sounded incredibly arrogant and you could easily tell he was a giant [insert your favorite insult] from a mile away.

    You could use the one that Carver dealer Jim Clark used to describe the proprietor at ASR a couple of days ago.
