Do you believe in Magic?

You have a keen insight into what others know and appear to have a command of all scientific knowledge and for that you are to be commended. And I suppose this is an appropriate place to thank the original designers of the CD for creating perfect sound forever.

"Perfect sound forever" Another good example of marketing hype. No science needed here. :-)

Not sure what is going on here. I don't believe in magic. One thing to keep in mind, don't overheat your equipment with this stuff. If that happens, it may go up in a puff of smoke! Just a possible scientific fact here.

A much more likely explanation, I would think, is that low level broadband noise (i.e., hiss) in the upper treble region is being reduced, and that is being subjectively perceived as a diminution of the highs.

I've seen it stated in a number of articles that I've read in the past that low level high frequency hiss tends to be subjectively perceived as "air" and ambience. Which would seem to make sense.

I've heard about this from several sources also. One problem I have with this is the fact I can still hear this hiss in the music I transferred to a CD. With this same music on the CD, it seems to have lost the those high frequencies, some of us refer to as air. Possibly, there may be a higher frequency hiss that we don't actually perceive, but may be there on analog, and cut off by the filter in the D/A converter.

One major problem with a lot of these tweaks is the fact that they are being used on equipment designed by Engineers with known scientific knowledge about how these things work.

If they didn't have this known and proven knowledge, we wouldn't have audio systems with analog, digital, and all kinds of other equipment involved in the process, used to make this reproduction happen.

If these Engineers go outside the limits of these known and proven scientifically proven facts, things don't work.

With the fact that they design these things with this known and proven scientific knowledge, and they say some of these things cannot work like this because it is outside the range of working proven parameters, it would make total sense to accept this. Don't forget, they designed, and made these products possible.

If it wasn't for these people with this knowledge, we wouldn't be able to discuss it here either. A lot of these tweak guys couldn't make any of this happen. These are just facts.

such as room acoustics and elimination of vibration, that are either overlooked or can't be addressed by the design engineers.

Yes, room acoustics, vibration problems, and other variables make perfect sense. This is still dealing with facts that are known. Coming up with new designs, such as better amps, D/A converters, and other new gear, yes. The same laws will apply in designing new technologies.

Science always worked one way. Changing that is not going to happen.
