Will cheater rob my PC's?

My REL Storm is dead quiet when connected to my Berning ZH-270 amp, but exhibits a low-level hum when connected to my new Art Audio Diavolo amp. Other than amps, all connections are the same. The REL is plugged into a different outlet than the rest of the equipment, but that's out of necessity due to location and lack of additional outlets. And as I mentioned, it's perfectly behaved with the Berning.

I've tried a cheater plug on the REL to no avail. The amps are connected to a PS Audio Ultimate Outlet which has had it's outgoing ground wire disconnected, so in essense, the amps have had their grounds lifted. The remainder of the equipment is connected to a PS Audio PS300, which is grounded.

I'm getting ready to try connecting cheater plugs to all the equipment with the exception of the preamp. But I'm concerned about the negative effect this will have on all my expensive power cords connected to this equipment.

Wouldn't the cheap cheater plug wipe out all the benefits of having a high end PC?

Any and all opinions are welcome.

My REL hums if my current amp is turned off. It did not do this with my old amp. It is fine with the amp turned on. Not sure why this happens. So I also shut the sub off first and on last.

I figure the sub somehow loses the ground on the Neutrik connection when the amp is off, but not sure. It is the same hum you would get if you disconnect the black cable from the amp with the sub on.
