Cable TV hum and related ??'s

My cable TV is causing a hum through my stereo. That is because I output the TV sound to my preamp, so I've got ground loop problems. I know that I could use a 3 prong to 2 prong adaptor, but would that negate the benefits of my after market power cords? Is there another way to remove the hum without disconnecting my cable?

There are several Isolation Transformers to do this, ranging in price from $4 to $50 depending on the company. I am unaware of the actual video quality differences, as I ran into the same issue and my local HIFI dealer sold me the $50.00 device. Nearly any mid - hifi dealer should stock these devices as the problem is common...

Here is some info:
- Mondial has a device called MAGIC. Mondial Antena Ground Isolation Circuit.
- Sonance RFGI1 is another device. Sonance has a web site.

Hope this helps..
