You really won't admit you are wrong here will you? There is nothing in those posts that allows anyone to prove or disprove. But you presented it as a sign of what an awful company they are. Not even were 25 years ago. Would it be too hard for you to admit you might have come on a bit strong with your example of them as "distorted and psychophantic"?
Given the product lines from 1982 to 1993 there is NO hybrid product. So yes, for that particular claim there is lack of credibility. And you are intelligent enough, post cuppa to accept that surely?
I think it got better since the 1st scans I viewed on the web compared to my memory its been rewritten, nicely formatted
still the basic thesis of "consonant distortion" should be easily seen to be flawed in light of IMD sum and especially difference products and very little additional Psychoacoustics knowledge of the Critical Band Theory, Masking

The part about "quasi-complimentary" amps not being capable of class AB operation should be fixed.

one test of the current cheever pdf for me is that search shows Otala is mentioned many times but Cordell, or Cherry not once
that is simple fanboyism - not expected minimum acceptable scholarship in a academic setting
since both of the latter directly addressed, refuted some of Otala's key claims in both theory and with built amplifiers, even custom measurement hardware to make TIM measurements in Otala's own terms

I fully support Bonsai and his designs. I have simulated his CFA power amp and cannot fault the design. BTW Bonsai, the word is spelled sycophantic, and there is plenty of it in the consumer audio world. Like Doug Self, I am an adamant critic of meaningless subjectivist language. As a regular reader of HFNRR over the years I have seen niche nonsense like pencil tubes, noisy nuvistors and other tacky, flashy marketeering. Your work is good Bonsai and I support you.
It's been beaten to death here again and again. I'm just not interested in doing it yet one more time.
if he's ignoring me though he's going to miss a lot of critiques, references, illustrative sims on the subject
There is a fair amount of discussion in this old thread: http://www.diyaudio.com/forums/solid-state/54702-nature-distortion-17.html
One comment was that Cheever says IM distortion doesn't occur in the absence of GNFB. I haven't read the thesis yet but if that is true it's nonsensical.
One might question the credentials of his committee, that's pretty fundamental sort of like the non-harmonic distortion.
I found the Cheever thesis very engaging! In fact, it is a 'breath of fresh air'. I am not in a position to say more, but I copied it entirely for closer examination. Thank goodness some people actually follow their opinions like I do.
I'm happy with the way feedback works. But when listening to what subjectivists say about feedback it pays not to throw the baby out with the bathwater. They may say 'feedback causes poor sound' but they don't know this for sure (feedback being a concept only, it has no causal properties), what they're reporting is correlation between global negative feedback and poor sound. I have a hypothesis for why this is so and if anyone's interested in it I'll set it out here for the assembled company to shoot down 🙂
Sorry but are you saying you support Bonsai in making stuff up just because he takes a particular view on the audio industry? And you've simulated his amp therefore it can't be faulted?
All Bonsai and now you are doing is proving that there is just as much BS coming from the "objectivist" camp of amateur commentators as from the hifi review industry. He's happy to present rumour from another unreliable source as evidence of how terrible MF is just to justify his stance on the industry as a whole.
For the record I have no association with MF nor any opinions on them as a company. The fact that Bonsai insists that I must just because I don't think it's right to accuse them of such dodgy practices without evidence says a lot about his morality and who has the axe to grind.
