What’s your vote for the most ridiculous, overpriced, and useless tweak?

Before moving on to the best, let me add my two cents about the worst.  Without a doubt, for me nothing comes close to the original Tice power conditioner (don't recall very well anymore, but it was some sort of frozen clock radio -- possibly).  I put it into my system and the result was if someone had dulled, squashed, and bleached the music.  I returned to the dealer seeking a refund.  She refused, say it was a special order.  Nothing else I have ever bought comes close to that fraud.

You probably didn’t burn it in long enough. 😀 These Quantum thinggies need some time to settle in. Frozen clock radio? Whoa, Daddy! That sounds eerily like....

I just pay 20 bucks for a china made schumann resonator.... The result are stupendous in my room and audio system...Better separation and imaging...Oups! wrong thread!

China’s a lot smarter than a lot of folks realize. For example China has the current distance record for quantum teleportation, 870 mi. I remember when it was few feet. Heck, they’ll be catching up to your humble narrator pretty soon if I’m not careful.

Hey, mahgister, quick question - does the Schumann device work on the system or you?
