Jack Bybee does NOT live on any income that he may make in audio. He was independently wealthy more than 20 years ago, before he retired. He does this audio stuff, because he needs a hobby, and he can never just relax and forget it. He did NOT buy his Bentley with audio earnings. In fact, I suspect that he barely breaks even with it, considering the hours that he puts in, and the high cost of raw materials in his products. I would not do it. I would rather sit around and input here. '-)

The same kind of increase of dynamic we use with level compressors, setting the attack time slow when this HF appears at high transients ?

I read on comments about those super tweeters that when you set a 40KHz sinusoidal signal, you do not hear nothing, but, if you start or stop the signal at full level of the sin, you hear a little noise pick at the start and end. IM products due to the high slewrate ?
The ear does react to the US energy by turning the gain down. And, the effect is exactly as you describe it..a feeling to be kind of deaf, ears plugged.

My experience was that the background noise would drop significantly when the US was turned on, and return when US was off.

I don't. The practical application of superconductors is not a trivial thing, nor are all the problems obvious. Even "simple" solder joints can cause millions of dollars worth of damage. CERN for example, the cost was 50 million in hardware, 50 million in labor. And soon, a 2 year shutdown to fix 10,000 joints.

Feynman was a theorist. The only time I am aware when he got involved with practical issues was when he reported to NASA about the Challenger disaster.

Possibly. Company spying and National Security spying are not the same thing. excpet when a company is working on something secret for the government. But higher levels are not done by contractors anyway.... we have National Labs for those things. 'Q' level spying will land you in prison for life in some hell-hole in a foreign country and forgotten about. Such a person would not be given a clearance at a serious level and would have been terminated. My clearnace took a year by FBI and CIA -- interviewing old neighbors and employers and school teachers and what your grandparents did for a living... all the places you lived and the like for character as well. One childhood friend I had not seen in many years, later told me 'they' came into his place of work and asked questions about what kind of person I was. I couldnt even find where this long ago person had moved to let alone where he worked. And, then you are monitored. Anyway-- were's the audio in this? Thx-RNM

RnMarsh,
"Q" it was......

I also have a cousin. was a PhD metallurgist with the Air Force until he retired. Now in private industry and gets to play with Star Wars development. Now if I could just get some former colleges to bring me into JPL I would have a blast.

It's in the rumble seat of Jack Bybee's Bentley racer.

Just about a (pseudo ?) scientist making fraudulent hifi gadgets whose effects can not be measured and manufacturing kept secret because it use some secret defense material directly issued from ET space vehicles. The kind of thing that I firmly believe in.

People love stories of conspiracy. In reality things are both much simpler and much more stupid.

I hear that they work pretty good, but not always. I might try them, sometime.
