"Great idea for the next generation of electrical components that may take decades to develop. Meanwhile, the real world beckons and requires action."
Do I strike you as a politician or something? I'm doing my best at the voting booths. You gotta start somewhere.
"Effective RFI trapping requires more than a big filter bank."
Not true. A good designer will be able to create a filter that works out near the GHz range down to somewhere slightly above DC using nothing more than the transformer and various capacitor types along with good PCB layout which includes parallel power and ground planes. Anything above a GHz will most likely be coming from somewhere external to the design for typical well designed audio equipment. Low footprint filters and shielded boxes will nearly eliminate these issues. See my response to Al for more details of my opinions on this. The near DC issues are the ones that are a real bitch to deal with without throwing major cash at. Luckily here in Seattle area near DC issues are fairly rare so I am fairly satisfied.
"Your "disconnect-conditioners-to-check-the-grid" idea continues to ignore the current reality of RFI. As for me, if I were to bypass my conditioners (and conditioning power cords), then it would always seem that the grid is noisy."
No offense but I can't help but wonder if this problem could largely be resolved by using better design techniques more appropriate to the RF problems you describe. Not saying I know anything about the quality of your paricular equipment, but in my experience thse types of problems can be engineered into the zone of being non issues but it takes a slightly different type of engineer, RF engineer, than what are typically found designing audio gear and/or the in house grid wiring layout.
