I'd like some tests, sneak into a audiophiles home and replace all his 'burnt in' cables for brand new ones or swap out some component..

It's a intresting phenomenon, even if it's just psychological I'd love to know what's really going on.
It's a lot to do with triboelectric effects, static, IMO. Lay a cable on the ground, the physical parts are in tension from being orientated in a new position - over a period of time the materials settle into their new orientation, and 'relax'. Yes, the effects should not be audible but I've learned to worry about this - best is to use cables that have least worries with this.

Yes, if you open a new interconnect cable that's been in a shrink-wrap package and without touching the connectors, measure across one connector using a sensitive high impedance voltmeter. You will see random noise voltages as the cable relaxes. But if you plug one end of another new cable into an audio source output connector, you won't see any noise.

What seems to be happening is that there is still noise there in many cases, just enough to be in that grey area on the edge of affecting audible qualities- the "did I hear something, or didn't I" space ... which is probably at the heart of lots of the anecdotal experiences of audio people.

Mechanical devices need breaking in and then, and then, well, they begin a slow deteriation from that point. Electrical devices need stabilization and then , and then, they sound their best from that point on (if done right).

I can't say I've ever concerned myself with 'break-in' for the stereo.

Another phobia avoided in my ignorance.

Did I miss a label?

" Do not run over 3,000Hz or at high load for the first 13.88 hours (1 billion cycles)."

Gee, that brings up some wonderment over how many cycles my woofer and panel have done over their 19 year life.

Does anyone make a zero-crossing counter for home use? Add an excursion estimator, and come up with a Speaker Odometer.

Somebody KickStart me!

He's often rude to King A, I don't like that and he is extremely dumb not that ,that is unusual on 'Whats a Brain' .
