Hum problem

Be aware that isolation devices can introduce little gremlins that will mess with some channels if you have digital cable. I had a Time-Warner tech come out when I first moved in because I wasn't getting several channels that I should have been - he isolated the problem as the Mondial Magic I had in line between the cable outlet and my cable box (which is connected to my DAC via toslink).

I felt pretty stupid, but then again, was totally unaware that those isolation boxes can cause such problems with the newer digital TV boxes (was a non-issue with the older, non-digital boxes I'd had in the past).

OK Which is best? The Jensen or ISO-MAX? Thank you all.

Jensen *is* Iso Max (Iso Max is the name of the product line). Look at the links. Both are selling the same Jensen VRD-1FF isolator.

A few minutes of your time could save you $50.

Not sure about the return policies of the two retailers linked in this thread, but I know Jensen Transformers offers a 30 day return for items purchased directly through them.

I *believe* Markertek's policy is the same, but check it to be certain before purchasing.
