Hi to all.
Perhaps I was not clear in my original posting that this is a thread to ask the OP a question and have it answered by the OP. It was not an open invitation for other designers to answer questions or give their opinions on my answers. The whole point is to give the public some insight on how I design things and how I evaluate my own and other equipment.
If you notice John Atkinson and I have similar views on what an amplifier ought to do.
If other designers want to have such a thread all the better. I would not care to comment on their thread because those are their answers, their views.
In the end I hope to educate. As far as selling anything I am happy to share the workings of my A/B test set up for no charge or build one for someone if they want to get into A/B testing.
I am most happy to discuss interactions in equipment, how I go about designing, how I listen. Far down the list is the sound of particular tubes or brands of the same tube. I will talk about what different tubes can and cannot do well. I can talk about how some circuits are more sensitive to tube rolling and some are much less so.
Now can we please proceed with this in mind.
Well, it turns out that it was my friend Ralph (we have never met, I simply call him my friend) who misspelled Charley's name.
It is in no way an excuse for bad specs- and in fact our amps have some pretty good specs (if proper measurement technique is used, which means **don’t ground a speaker terminal during testing**, which is the mistake that almost everyone except Charles Hanson made/makes). I suspect you didn’t read the paper at the link very carefully, since you claimed that you read it, yet still with the remonstrations!Sorry. Now back to my sorely missed idol, the great Charles Hansen. He gave an interview to S'Phile back in October 2016 (or at least, published in that issue) and said this;
My point being that here we have this great engineer who thought he had engineered a product that tested well and sounded great and then he had an epiphany of sorts that something better was indeed out there and attainable. I continue to believe that old maxim that we're all tired of reciting let alone hearing; not all things that matter are amenable to testing.
In a separate post your "intake guy" Clio-something really gave me the business about being a troll and not having anything technical to add. He's kind of right and kind of wrong IMHO. I may not have technical expertise but I will never believe that JA's measurements trump listening impressions. Roger-the Roger that I have metaphysically shaken hands with-enthusiastically too-you have endorsed JA's measurement techniques again and again and yet the fact of the matter is that JA has never given any tubed amp an enthusiastic endorsement from the standpoint of measurements. If your amp is an exception, than fine, that would be one instance of my "never" being incorrect. He may have given that monster hybrid integrated by Musical Fidelity-a known S'Phile darling-a thumbs up from a measurement perspective as well. So that would be two exceptions.
Btw, go back to the full link of Charley Hansen's interview and see what he said about finding a power cord laying against the carpet at a show and finding that one wood block cured his perceived dissonance. What do you have to say about that? That it was in his mind?

Actually, I said you bring zero value. The statement wasn't referring to just technical value. Perhaps you got confused with the other part of the paragraph where I said you lack the knowledge or credibility to refute anything Roger says. I was in fact referring to your lack of technical knowledge in that instance, but of course you already copped to that previously.
