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?

Ldatlof - the only Sirius home dock I know of is the Audiovox, and it uses a wall-wart power supply - no AC fed to the unit. In all siriusness, if you're using an AC Enhancer on a wall-wart, your house has already burned down, and you were in it.

Tbg - your obviously fragile and still-bruised ego is showing.
Easy explanation - you posted an attempt at a snide remark, aimed solely at me. Apparently your little feelings are still hurt.
Hi Rex. It is an audiovox home dock as you have surmised.

I am ready for some more abuse. What's a wall-wart power supply? I admit that I don't know much about electricity, but why does it come with a three pronged plug that you are supposed to plug into the wall if no AC is fed to the unit. I have it plugged in to the AC Enhancer so that everything turns on/off at the touch of one button.

As you can see my house hasn't burned down - yet.
Wall-wart = "A small power-supply brick with integral male plug, designed to plug directly into a wall outlet; called a ‘wart’ because when installed on a power strip it tends to block up at least one more socket than it uses...."

So now that I know what a wall wart is I can unequivocally say that the Audiovox Sirius Home Dock does not come with a wall-wart. The power cord has a standard three prong plug on one end and a mini jack type at the other. In the middle there is a brick which I guess can be called a wart. But you can't plug it into a wall.

So Rex, my question still stands. Is the home dock grounded when plugged into the AC Enhancer via a cheater plug? Tbg says no, what say you?
