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

How about SHM-CD’s from Japan....they turn out to be nothing more than just clever marketing BS!!!

Power cables.  When people buy $3k speakers and $4k power cords for them, something is really wrong.
No, actually the SHM CDs from Japan employ a significantly more transparent plastic material than the usual polycarbonate, which only about 91% transparent. Better transparency, better signal. Like you know!
Decoupling the printed circuit boards from the chassis, including removing screws, is a way better idea than using special screws. For example, use cork squares to decouple the circuit boards from the chassis, and remove all or most screws. This is especially important if there’s a large transformer inside the chassis.
