You concerns are genuine. My power filter, which feeds my entire AV system, has a GFI and the unit itself is properly grounded through its power cord. If I found a CATV ground isolation transformer worth a darn, I could ground the system at the amplifier through the amp's power cord without hum. I share your frustration on this topic because I have never received a clear response from anyone, except in the archives here. The best I can figure, if you float the CATV ground with a MAGIC, or similar, the CATV box's ground path would still go through interconnects to get to the amp. Since I have never seen a CATV box with a grounded AC cable, I prefer to keep it grounded in accordance with the NEC and not use a CATV ground isolation transformer. Please respond as I would like to nail down this issue, even if it means I must change my setup.
