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


My vote: Furutech Outlet Cover 105 NCF $220, with “special crystalline material that has two “active” properties.” https://www.thecableco.com/outlet-cover-105-ncf.html

Pardon me, I'm going to go cryo my rabbit to see if it becomes less directional...
Nordhost Odin Cables/Wires.  To connect my pre-amp, amps (two), disc player and speakers (not including power cords) $137,000.00.
I find it rather curious that the standard byline is "the better the system the more it needs tweaks".  One might think the opposite should be true.  
Strawman argument alert! Bad Jitter, bad!
