"The point is ICs should never be used as an effective means for an AC power ground fault circuit current path."
OK. Yet they typically will do the job just fine, especially the shielded ones which is why I expressed it that way. Remember the issue is the fusing current, not the long term load.
"Something else that should be considered is not all designer/manufacture of audio equipment connect the signal ground to the chassis equipment ground."
True, but that didn't used to be as common as now. And indeed the practice may be helping to contribute to the dismal RFI rejection many experience. Additionally in a stereo there will often be noticable hum or something where in, say, a floor lamp, a stray strand from the hot can touch the metal housing and still light just fine. The newer polarized plugs do help with that...
