OK, this is a bit of an odd question, but I'm going to ask it anyways. I have the Outlaw 7500 (and love it) connected up to a Yamaha RX-V1600. Right now it is connected via Outlaw RCA cables from the pre-amp outputs on the Yammie to the RCA inputs on the 7500. Originally, I had a fair bit of the ground loop hum, which I tracked down to the cable line (95% sure). I installed the Jensen VRD-1FF Isolator, which did get rid of the hum (woohoo!). However, occasionally some of my HD channels suffer from macroblocking artifacts and sometimes the tuner is not even able to tune in the station all together. My other HDTV with no audio system connect, just audio from the TV itself, doesn't seem to suffer from this problem whatsoever.

Long story short, Markertek seems to have some RCA to XLR cables that I hoped might allow me to remove the Jensen isolator and also not have the hum. Do you think that this might work?

I know that the real problem is to fix the ground loop problem, but the cable company insists that the cable system is grounded correctly, and I don't want to use one of those "cheater" plugs.

Thanks for your input,

Tom
