Not useless but completely overpriced Shun Mook LP Clamp $3200.00 ! I'll sacrifice the improvement over my Purist clamp and use the monies for tubes etc.
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
