Can someone please explain how these discs work? Anyone? Sans any kind of reality based explanation or double-blind tests that truly validate these discs, the only rational explanation for their powers lies in your own mind-- it's called the Placebo Effect and it is indeed very powerful-- you will hear differences, things you never heard before, and perversely, if I snuck into your house and removed those little discs without your knowledge, I would be willing to bet anyone here that you would still hear those same improvements, until it was revealed the little discs were removed. The mind is a powerful thing, one can convince one's self of almost anything.
The only thing that bugs me about little magic tweaks like these are the stupid money prices being charged for so many of them. Like a $5000 record weight's claims that it sounds better than any old $100 version of same.
Again, want to place a few bets?
