What commerical audio system tweaks provide sound quality improvement??

@geoffkait  "I never turned off the power prior to cleaning outlets and am fine. I mean except for a slight twitch."

Bad advice, Geoff, in my opinion.

Perhaps you know enough to do that kind of thing with some safety, but not everyone does. I suggest you withdraw that.

I dislike the idea of editing to prevent people from hurting themselves. Geoff did say not to clean hot and neutral at the same time. Which is fair warning. 

But if a bunch of us say it's foolproof safety to turn off the circuit, which it is, then anyone reading this can decide how to proceed.

@geoffkait I was thinking of the pebbles with the 'special crystal structure' that you tape or place on cables and components. It's a bag of rocks from a roadside attraction anywhere in the southwest...

Caig makes a good cleaner and a liquid polymer that is conductive

Don't waste money on spendy interconnects but gold plated ends are worthwhile.

ARC puts dampers on their tubes so you should too; turntables & cartridges would be best in another room if you cannot isolate them from surface vibrations as well as airborne vibrations.

Add that to what todd said above and ignore the trolls

Nitwit convention in progress. Please stand by. Randi is apparently applying the conductive fluid with his fingers.
