No one can tell you whether/how your system, room and/or ears will respond to some new addition. There are simply too many variables.
LIKEWISE: no one can possibly know whether a new addition (ie: some kind of disc, crystal, fuse, interconnect, speaker cable, etc) will make a difference, in their system and room, with their media and to their ears, without trying them for themselves.
Some companies offer a 30 Day Satisfaction Guarantee, so- those that are actually interested, have absolutely nothing to lose, by trying (experimenting with) such.
Anyone that knows anything about the sciences, realizes that something like 96% of what makes up this universe, remains a mystery.
For centuries; humanity’s seen, heard, felt and otherwise witnessed phenomena, that none of the best minds could explain, UNTIL they developed a science or measurement, that could explain it.
The Naysayer Church wants you to trust their antiquated science (1800’s electrical theory) and faith-based, religious doctrine, BLINDLY ("Trust ME!").
Theories have never proven or disproven anything. It’s INVARIABLY testing and experimentation that proves or disproves theories/hypotheses.
IF you’re interested in the possibility of improving your system’s presentation, have a shred of confidence in your capacity for perceiving reality and trust your own senses: actually TRY whatever whets your aural appetite, FOR YOURSELF.
The Naysayer Church HATES it, when THAT happens!
^^^ This is as perfect a product of scientific ignorance as one would like to find.
It's the life-blood of companies that sell products with dubious technical claims.
You can see exactly that attitude repeated over and over from every fringe belief system showing up at your local New Age and Psychic Fair.
"Only YOU can tell FOR YOURSELF if these Healing Crystals work! Trust Yourself and your perception Above All"
It's basically the epistemology that ran rampant before science arose. It misses out precisely on why science had to arise: Yes, test. But, *control for known variables* (which include your ability to fool yourself). If you aren't doing that, your tests are no more rigorous than those used for bloodletting or the Power Of The Local Witchdoctor to Heal.
