Unicorn from Dan came in the mail today. Suppose to be magic. I am de-gaussing my headphone cables ATM but it can do other things like dampen vibrations of your hardware. Make your data bit perfect and jitter free. If your headphones are high ohm it will raise the voltage of your amplifier to match. It will jack up the current if you have a low ohm headphone. Yes that is the official technical term Dan used, "jack up". So far the only sonic difference I am hearing is my daughter crying tying to get the unicorn.
I'd never jack up an unicorn. Too tempermental.
It's only when you treat them nicely that they'll begin to reap in delicious unicorn mayonnaise for harvesting.
Seriously what is that though?
