Do you believe in Magic?

a connotation of magic might be something which is perceived but has no objective basis.

i don't believe that magic exists in the empirical world. i believe there are perceptions which cannot be explained, using scientific principles. either the perception is erroneous, or engineers and "scientists" have not yet discovered the parameters necessary to measure or explain the perception , objectively.

the problem with subjective judgment and sense perception is the possibility of hearing that which is not present , or failing to hear that which is.

.

so, it would seem that magic is a term which may be used, when someone has no explanation as to the occurrence of an event.

there is an explanation. however, it remains to be discovered by a brilliant person.

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.

These tweaks, if one assumes they work, seem to indicate that the knowledge of the design engineers is either not perfect or there are other factors one must consider besides electronics circuit design and speaker design, such as room acoustics and elimination of vibration, that are either overlooked or can't be addressed by the design engineers. Knowledge is not an absolute and continues to evolve. They do the best they can under the circumstances. :-)

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.

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.
