    I was just on Bluejeans Cable looking at their cables for subs and saw they have an isolation transformer to be placed in line with the sub (RCA connects). All isolation transformers I've read about thus far have been to deal with the ground loop at the satellite or cable box and use RF connectors. I can't find any data on the specific product (short of asking for it from Bluejeans) but am curious how well it would work. Anyone have any experience with this?

    Checked with bluejeans and it is the Calrad 10-78-RCA, specified to operate up to 50 kHz. I checked with a local electronics shop and it was able to order one for me for less. I've been trying to track down a slight hum in my sub for some time and I haven't been able to definitively determine it as ground loop or EMI. So I'll give the transformer a try and bluejeans' sub cable, which sounds like a beefy, highly shielded sucker.
