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

Isolation 101, not for the squeamish...

LIGO uses glass threads to isolate the mirrors. 🤭

See LIGO video,

Connection 101, not for the uninitiated...


Anything that connects to another something is a connector. To a certain desirable extent it can be an isolator, too, but is a connector.


Which property practically prevails depends on multitude of factors, but isolators mentioned earlier are connectors.

In the link above, as removed from pertinence about audio reproduction as it is, there are two moments that emphasize limits of isolation.


At around 2:45, word "relatively" and at around 6:45 "bonding them" ("connecting them", one could say).


In fact, there is much more later in the video, but those two are enough for aspiring novices.

Calm down, Glumpy. They’re all isolation devices and they all touch. Springs, roller bearings, bungee cords, air springs, inner tubes, magnetic levitation, the giant slip plates under the new Apple 🍏 HQ building, you know, the one that’s a mile around the circumference. Oh, and string.
