Is cheater plug safe with grounded monster power?

I recently plugged in a new amplifier into my monster power HTS-2600 and experienced a loud speaker hum. Applying a cheater plug to the amp outlet on the HTS-2600 completely eliminated the hum. My question--and excuse my ignorance--is whether it is safe to use a cheater plug to the amp outlet of a power station that is itself properly grounded? Although the temptation to continue using the cheater plug is high because of improvement in sonics, I am not comfortable because I think the amplifier without a ground to the power station would not be protected even if the power station is grounded. Am I correct in my logic? I thought a cheater plug was only safe when used with old 2-pronged outlets to allow use of 3-pronged plugs and attaching the cheater plug wire to the screw of the grounded outlet?

If you ground the amp as Gregadd suggests to the wall receptacle, you will have the same ground loop. Ground only the amp to a real ground will not cause the ground loop.

I could be off base here but I wouldn't use the Monster for my amps in the first place. I would try doing the amp into the wall and see--or is that listen?

Nothing would be harmed. My guess is that it would sound better.

I dont know if its safe. But why would a company like PS Audio sell Power Cords with removable ground pins ?

TBG. I read both of your posts.I could not understand neither. A three prong converter which acccepts a three prong plug steps it down to a two prong plug and ground wire. That wire is designed to be attached to the screw of recptacle that holds the faceplate to the wall. I assume that when he used the cheater plug he was left with no place to attach the wire. It is not requireed that third wire be attched to the screw of that faceplate. It can be grounded to any structual metal. I ground my turntable to my preamp. Respect Electricity!
