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

Tice clock? First time I saw it- in a store in NYC, I thought it was a gag. 

Peter Belt's stuff is in the realm of voodoo, IMO. 

Cable lifts? If that's your thing, a good hardware store can sell you rebar separators that work perfectly as cable lifters. Under a buck a piece. 

The Clever Little Clock is much crazier than the Tice Clock ever thought of being. The Clever Little Clock doesn’t have to be plugged into the wall outlet. I mean, come on!

Zavato The Nordost lift have Titanium. That makes them special.

Magical rocks you spread around the listening room.
Red and blue crystals that are  put on your tonearm.
Fairy dust.

Re - the PWB red pen. This tweek wouldn't work for me at all. The term "Past" is not dominated by all that is "black evil and horrible". For me, it's where all the best recorded music exists. The "Present" is black evil and horrible.
