Three computers
An 802.11g wireless router
Three digital cable boxes
Four CD / DVD players
Four wireless phones
Two cellular phones
A digital burglar alarm
A digitally controlled stove
A digitally controlled microwave
A digitally controlled washer
A digitally controlled dryer cabinet

I find that unchecked RFI manifests itself as a bright, tizzy glare added to the music. Removing it with shielded cables of all sorts restores low level resolution.

Interesting, I have at least the same number of devices you have, though I think at peak time, only 3 or 4 of them are simultaneously activated. I've never noticed any "tizzy glare" in my system, though I have shielded cables right now so I'll have to swap in some other ones to perform that basic listening test...

I don't have any idea what the metric is. Nor do I need to know. The fact that you are able to "shield" against it justifies that there is in fact a property you are guarding against. It must have diferent levels of intensities, as you've related it to the presence of your devices. The specific metric, I don't know, maybe it's LCR maybe not. I think you've missed my earlier point though. If your measurements aren't explaining your observations, you're using the wrong measurements.

Mathematics and science didn't start with all the answers. Conside our simple numbers system. We started with integers, moved to rational, to real, to complex or imaginary numbers etc...there's an obvious progression. It usually starts with a question such as yours, followed by pursuit of the answer...sometimes getting that answer takes longer than we'd like.
