What sounds like morning mud to one guy might sound like morning wood to the next.

Yeah. I'm not saying that two amps won't sound different to an extent. Any two amplifiers will vary by no more than the maximum variation of their respective transfer functions.

I'm just saying, when the cards are on the table, such differences are often difficult to perceive. That's the whole gist of Carver's "T" series amps. They're transfer function modified to mimic a competitors sound at a fraction of the price. At least, that's how they started out.

Roger Russell is a crackpot and a hypocrite. ABX testing for audio is worthless.

Quote
Blind tests nearly universally appear to indicate that no differences exist between electronics, cables, capacitors, etc. In fact, one infamous test "revealed" that no sonic differences exist between power amplifiers. Mark Levinson, NYAL Futterman OTL tube monoblock, NAD, Hafler, and Counterpoint power amplifiers were all judged to be sonically identical to each other and to a $219 Japanese receiver (footnote 7). This very test, wielded by the objectivists as proof that all amplifiers sound alike, in fact calls into question the entire blind methodology because of the conclusion's absurdity. Who really believes that a pair of Futterman OTL tube amplifiers, a Mark Levinson, and a Japanese receiver are sonically identical? Rather than bolster the objectivist's case, the "all amplifiers sound the same" conclusion of this blind test in fact discredits the very methodology on which hangs the objectivist's entire belief structure.

For those that want to spend some time learning the truth about duo-trio balanced reference tests (ABX) as it pertains to audio the following are a good read.
 
"Sensory Evaluation Techniques" book and the "Sensory Testing Methods" manual which is published by the American Society for Testing and Materials. Also read, "Perceptual Audio Evaluation-Theory, Method and Application."
 
For those that just want to cut to the chase, summed up by a well respected member of the audio community,
 
Quote
The peer-reviewed scientific literature and textbooks authored by credible, reputable and respected professionals in the sensory science and audio performance evaluation fields indicate that blind tests, ABX tests, duo-trio balanced reference tests or any tests of that ilk are scientifically invalid and totally inappropriate for sound stimuli.

And,
 
Quote
The ABX test (actually called a duo-trio balanced reference test) is not indicated for the class of sensory stimuli in which audio equipment evaluation falls. In other words, applying ABX testing to audio equipment evaluation is actually within the realm of pseudo-science because it inevitably leads to erroneous results. Therefore, the descriptor "believer" would more appropriately be applied to the naysayer or anti-audiophile since their thought processes are driven by, and based on, data which they "believe" to be right, but which has no verifiable basis in reality or in accurate and correct scientific procedure and theory.

It is ironic that a group of individuals who rail the hardest against "pseudo-science" and who scream the loudest for scientific verification of audiophile claims insist on using a test that is scientifically inappropriate and scientifically invalid for the evaluation of sonic differences in audiophile grade equipment. Even more tragic is the fact that the ABX test is highly error prone even for the sensory phenomena it is appropriate for.

I had no problem telling the difference between  Carver's "T" amps and Carver's tube amps. It wasn't even close. Just saying.

Well, either my ears are blown out, I have no clue what I should be listening for, or I'm one of those idiots who doesn't want to hear significant differences between amplifiers. Some sound slightly "better" and some sound "worse", but that's entirely subjective.

I remember the first time I heard an MC275. I was taken back at how much different it didn't sound as compared to everything else I'd heard up to that point, especially considering all of the valve hoopla. Or maybe I thought it didn't. I wouldn't mind being proven wrong on this. I've just never heard otherwise with my own two ears. Or maybe I don't allow myself to do so.

I need to add that I agree that the prestige of seeing a nice expensive shiny amp, or to feel the warm thrill of confusion, that space cadet glow (in the case of tubes) is definitely part of the drive to buy better components. But, if they all sounded the same I would still be listening to a 1994 Teac 100 wpc receiver.
I am confident that an SL-1200 is capable of outperforming turntables of much higher expense with minor modification.

I would just like to vote for Carver and the hope that WE All can appreciate the quality sound of superior equipment.
IN REALITY IT ONLY MATTERS WHAT IT SOUNDS LIKE TO YOU!!!!!

Checked the DC offset and:
Left 16mV
Right 30mV and climbing about a tenth every 2 seconds

Yes, the right channel is the one that seemed weaker.

Were you able to adjust it?

I haven't tried to adjust it yet. I Left the amp on for about half an hr and rechecked and the right channel had peaked at 36.6 mV. I think I am going to repair the output devices.

Spec is +- 20mv.   30 is not bad but should be addressed. My feeble memory ::) tells me that there is nothing on the board to adjust offset.  You need to find the leak.
