You sir, are a slanderer of a deceased person, loved by many in the audio community. The STRONGEST thing that he did smoke was tobacco, and he drank only a beer or two, on occasion. I knew him as a business partner for about 10 years.

Clearly, we have a different sense of humor. If you don't grab the twist, I'm sorry, but this time I'm not gonna explain it to you.

edit: BTW1, I really don't care if someone smokes or drinks, rather what he is actually doing under the influence of 'something'.
BTW2, now it's time to visit my local pub.

John,
I believe the rule of the scientific method is that hypotheses are considered suspect until objectively tested. Not, every attractive idea should be considered valid until tested.

The Bybee products may well do what they claim, for some customers, I have no idea. But I consider this a hypothetical claim in the absence of testing.

Leaving the aspect of a progress in science in general aside, what is the benefit of an objective proof for a potential customer?

Let´s assume there was a positive, objective, reliable and valid test result somewhere; does that mean everyone has to feel the stunning experience or has a potential customer still to listen for himself?

If he has still to listen for himself which way should he do it?
Isn´t he still able to fool himself about the stunning experience?

Otherwise if he is able to get a useful listening result himself, why would an objective test from other people be needed? 🙂

I was simply pointing out (as you are so found of doing) that you had made a statement that was completely unsupported by the anecdotal evidence you provided. What evidence do you have that these people died as a result of the treatment chosen?

I made no such statement. I simply stated two facts both verifiable, everyone is free to make their own conclusions and choices. In the face of evidence I would probably not pursue a course of exclusively homeopathic care faced with any potentially fatal ailment. As some of SY's examples show innocuous problems can turn fatal if not treated.

You seem intent on taking all criticism personally, I can't help that. Getting to the bottom of a circuits behavior has no reflection on the designer. As it appears here (Blowtorch) the actual circuit has drifted into obscurity and aural homeopathy has taken the forefront.

Jakob2,
Oh, my point is about misleading advertising. Deception.
I think the principle I am following is that the duty is on the seller to validate the claims the seller makes, as they apply to customers in general. Whether a specific customer then benefits from these claims in full or in part is not guaranteed. But the seller must be able to back up the claim he makes.

I think the ethical approach is to seek to protect the consumer against their own potential gullibility.

I know perfectly well what was meant. It was a slander on Bob Crump's judgement, due to an implied interest in mind altering drugs. BUT Bob only liked coffee and cigarettes, so his judgement could not have been impaired by mind altering drugs.
I, of course, know what pot is, and have tried it over the last 48 years. I don't like smoking ANYTHING, just a personal sensitivity to smoke, but most of my friends enjoy pot, on occasion. I prefer to drink, sometimes to excess. IF I was not on Prozac at this moment, I would pin a few ears back so badly that I would be banned from here, just on general principles. However, I keep my meds up, so I can 'roll with the insults and insinuations' to my friends and myself, and try to stay within guidelines.
What always comes back to me is:
A scene in the movie: 'They call me, Mr. Tibbs' where a black actor is slapped in the face by a Southern racist, and he slaps him back in return at almost the same instant. It must have unsettled a number of Southerners when the movie came out at the time.
That is called returning in kind what you get done to you, but it is not allowed in general society.

Jon, trust me, a few extra dB of noise reduction in the fet IC would have almost NO measurable effect if it were used in the BLOWTORCH, instead of the open loop, all fet design. This is because of the volume pot that is at the input, and the rather noisy mosfets used in the second stage of the BLOWTORCH which degrades the low frequency noise of the line amp.
