All the power related stuff sounds reasonable. I don't get the breaking and re-establishing IC thing, this has nothing to do with power issues.
I don't recall if this has already been mentioned, but it sounds like you may have an over-voltage situation as well, this causes hum in my isolation transformer. Other than the hum, I haven't had any other issues.
Proper grounding of dedicated circuits is absolutely critical as well. As I previously mentioned, you should get all equipment off the non-dedicated lines, all kinds of crap rides in on shared grounds and mains. Digital will benefit most from clean AC, all your video equipment should be on seperate lines from audio equipment.
You should have 3 dedicated lines, one for amp, most likely straight into wall, another for CDP and preamp, a third for video components. You'll never get to the bottem of anything until you do this.
Next, get a quality power conditioner for digital and preamp, maybe amp. At this point you'll be able to make a correct diagnosis as to possible issues with the sonic palatte of audio components.
