Recently, and with an APC power strip with coax (cable antenna) in/out, I had a eureka moment. For whatever reason, I've always conveyed a buzz through the speakers with this certain amp (not an Outlaw). The ground loop type buzz occurs only when the Cable service is connected to the TV in which the stereo is also connected. Two houses in two states had the same ground buzz problem and the cable company(s) can't fix it. It's my big amp not shunting this noise. Long ago I found a certain 75 > 300 ohm adapter that contained a resister inside that stopped the buzz. I had the 75 > 300 > 75 ohm adapter(s) in the cable co. box outside the house for best affect. One day I observed my stereo was buzzing and went out to the box... my adapter rig was missing! I went to the Shack and got another but it didn't work... I found the cable company had come to the house, saw my adapter in the chain and took it off. Fortunatly, I was able to get the cable tech to bring it back to me, and that's when I discovered the special nature of the one adapter with a built-in resister. I actually havn't found another like it... until now.

Normally, I keep the signal path a short / clean as possible, but I tried the new APC power strip's coax in/out in the cable TV chain and it stops the buzz even more cleanly than my 300 ohm adapter. Plus I don't have to go from 75 to 300 ohm and back so the TV picture may look better, but that might just be imagining. Apparently, there is a simular resistor inside the APC (eleven outlet) power strip coax section. I have a few different model APC power strips. The white one labeled "Professional" does have the best outlet feel. I use one with the highest joules rating at the power amp and another (previously described) around the TV/AV gear. All have never failed and the Pro one is 14 years old, lights still don't flicker like other brands I've had.

My brother has a PS Audio power strip/line conditioner that is the most substantial block of aluminum I've ever touched. That is one sexy power strip. If $ wern't a factor, I'd be having one of those... as long as it stops the buzz.
