Or hummmmm. Trannies have a tendency to hum. Lots of explanations, but there you have it. If it isn't loud, like a ground loop can be, then you'll just tune it out eventually, after you do what you can to mechanically damp it.
As to what you're calling isolation, well, not sure what you want. But here's a stab at it.
I found that I had a DC loud hum whenever my wife turned on her hairdryer in another room even on another circuit. It came from my sub. (I had other sub hum problems that weren't ground loops, but that's not relevant here.) At another inmates suggestion I built one of the simple DC blocker circuits, many of which are posted here, built it into a power strip and plugged my sub into that.
Result was no discernable limit to dynamics, but complete blocking of the DC buzz from my wife's hairdryer.
This kind of DC blocking might be what you're seeking. I'm told that it might limit dynamics on analog amps, however, so it isn't a cure all.
As to other AC tweaks, there are many posted here that you can DIY (or buy if your pocket is big enough). They DO work in my system and in any others that I've worked with at friends, both audiophile and not.
Of course, if you can't hear the difference, why pay for it? Try it from a commercial source that permits full refund returns. What do you have to lose?
