I stand corrected! A little bit of web research shows that this would be
a venture capitalist's dream. I have to continually remind myself not to
overestimate the golden-ear crowd -- after all, the gold-plated 8 ohm
characteristic impedance speaker cables sold (and I assume still sell)
like hot cakes. The placebo effect is certainly powerful, but it's
possible that the "quantum purifiers" might actually do something.
Rather than believe that the purveyor is actually selling components
whose composition is "classified by the U.S. military", I'd be willing
to bet they're some sort of more-or-less off the shelf varistor. That
would flavor the music a bit, and anyone who'd just dropped 600 bucks
for a pair of them would no doubt find the flavoring to be marvelous. A
few minutes with a curve tracer and some web specifications should pin
the source down pretty quickly. But I'm not quite 600 bucks curious. . .
