Tvad - ground adapter plugs are sold so that you can connect a device requiring a safety ground connection to an outlet that does not have a 3rd ground pin, but HAS A GROUNDED OUTLET BOX. It is not designed to allow a device requiring a safety ground to be used without such a ground.

A grounded outlet box is one where the box itself is grounded. If properly grounded, the wallplate screw will be a path to earth.

That is why the adapter plug has a metallic clip or pigtail to connect to the grounded wallplate screw. It is permissible to use this approach, thus the adapter plugs are legal to sell.

Using the adapter plug without connecting to ground is "cheating," which is why it's called a "cheater" plug. Using it to defeat the ground is against NEC. NEC has the force of law in pretty much every locale in the US, so it's illegal to use a ground adapter as a "cheater" plug.

Also, installing new outlets without proper grounding, as you suggest, is illegal, incredibly dangerous, and stupid. If you had a problem because of the installation of an illegal electrical system, your homeowner's insurance could legally refuse to pay any claim.

Many ground loops are the result of dc on the cable tv line or dss. If you have video hooked thru your audio system and have a bad buzz going, remove the co-ax cable from the input of the cable box or dss receiver..If the bad buzz vacates, then the problem is on the line..Also if you have several pieces of audio hooked to 2 or 3 ac outlets you may be encountering different ground potentials which will give you an offset and result in hum or a bad buzz.Tom

Thanks everyone for trying to help me.

Here's is an update to my situation. I went today to a local stereo shop and explained my problem. He suggested that I purchase a Audiophile APS unit. The 700 watt version retailed at 2700.00 Cad a bit out of my price range for now.

Just to set things straight I've tried disconnecting my cable entirely and the buzz still remains. The video is hooked up to my Monster Power Bar and from there to my TV.

All of my components except my amp are hooked to my power bar. The outlet I'm using is a switched one by that I mean a wall switch cuts all power. I've tried tackling this problem before by unplugging all house app and switching outlets the buzz still remains.

I thought some fresh blood this time around might give me some fresh insights.

Many Thanks
