Vett93 (nice year ;-) Good question! With regard to switching power supplies (and Class D amps) I'm not an expert. I've certainly not encountered anything like what you mentioned.
I do know they are not all created equal (equally good or equally bad ;-) Some are analog controlled others digital. The care with which filtration is implemented is also a big factor in eliminating potential problems. So I don't think it would be fair to tar them all with the same brush ;-)
I know that Exactpower and the few other makers of regenerators for audio use, isolate all outlets from one another and in most cases even provide some of the outlets with 'digital filters' (usually nothing but a capacitor across the line ;-) Anyway, I don't think one needs to worry about modern high-quality class D amps putting junk back into the cleaned-up power. Early car audio subwoofers were another story altogether, but in that application, ELIMINATING noise was probably considered counterproductive (he said as he rolled up his window ;-)
