John Curl's Blowtorch preamplifier part II

This, we think, is an important key to quality listening.

No doubts John that envelopes and their intermodulations with musical sounds cause distortions which spectra are not arithmetically related to multiplications of their fundamental frequencies by integers. For instance, why I decided to replace internals of MXL-770 microphones, because it was too well audible how envelopes, especially of sibilant sounds, intermodulated with them causing harsh unnatural sounds that were remotely close to sounds of small peaces of a broken glass.

Please, just talk to Dick, Scott, rather than challenging me. I already showed you 'inharmonic' distortion products, you just have ignored them.

However, I am on the path of enlightenment, so my questions are answered by people with more experience than me in specific areas.
The hear no difference, measure no difference crowd are going to have a different dialogue with someone like Dick Sequerra. It just isn't worth it to him to bang his head against the crowd, and he chides me about wasting my time with dialogue on line, when I could be doing something more useful.

But it does concern me, and Bob, and Edmond and Syn08 and Wavebourn and Scott and a slew (no pun intended) of other people, who hear you go on about inharmonic generation without telling us how and why. It's maddening! We ALL want to know!
Just post Dicks number and we all can give him a call. Unless he can post his reasoning here? I mean, he's not AFRAID of us, is he?

Give me that $10,000 and I will send you a record of remains of a snare sound, after nulling-out the original signal.

Wavebourn, please keep on target. No microphones at this time. Also, you should actually learn what I am talking about, before going off on a tangent. This is why we go in circles, rather that forward. For example, maybe you should look at the paper that I am referring to.

John;

we are going in circles because you keep ignoring what people are saying right on target, and the single thing we can learn from you is how to avoid direct answers referring in circles to something out of the scope of the discussion. I.e. how to contribute to prolonging the discussion without adding any meaning to it's content.

Can you give us some clue how that mechanism would work? I guess the envelope has a spectrum?

No, Dick does not think too much of the bunch of you, and for him, this sort of nonsense would be a complete waste of time.

So, he (through his proxy, you) tells us something, and then if we ask him why or how, he 'doesn't think too much of us'? Is he really such an antisocial, mean, frustrated and cowardly person? If so, why don't then YOU tell us? I mean, you're privvy to his most intimate thoughts, surely you are authorized to share his deep thoughts with us? Give us a break!

Sure it does. That's the point.

Any music has more of frequencies than fundamental frequencies of sounds and their harmonics. Sounds have attack and decay; even when you take as an example a sinusoidal signal it has wide specter, because the sinusoidal signal has both start and end.
However, John commanded to stop talking about microphones, because it was the explanation, right on the target, without involvements of his friends and papers.

So, I am silent from now, in this thread, until some technical discussion will be allowed.
