You'll want to find a product that will use a transformer to lift the ground rather than those 2/3 prong plug adaptors.

In my rig, I don't lift grounds. Period. I do have individual ground lifts per channel on all my inputs and outputs on my 56-channel snake, and my monitor routing is ground isolated and run down a Cat5e cable.

A company that starts with the letter E and ends with Tech and has a "b" right after the first E makes a fairly good line of products that should be able to address this issue.

I think you might also check to see where your DMX controller is plugged into. Is it on the same cirucit as your main mix position? Is your PA in the same cirucit? If so, your DMX cable is facilitating the ground issue. If it was an XLR, I'd recommend removing the connection from shell to shell and sever 1 at the male end. However, I don't like removing the shield connection on Pin 1 and all my cables are standardized. I forget what pin is what in a 3-wire DMX, but you can remove your ground since all they are really using is async TX and RX anyways at a fixed DTE, nothing major. Still, I try to not lift ground in data cables either.

I'm not using any intels or movers yet, so I can't comment further. But definately "divide and conquer". You need to discover the true source of the problem. I personally have not had any issues yet.
