Rather than use cheaters I disconnect the ground wire at the IEC end of my PC. Of course, you can only do this if the PC has a removable plug, like Oyaide, Watt Gate, etc. Only my preamp is grounded and I do hear a reduction in noise, but depending on the amp I'm using, it may not solve all the problems.
I've been told that if one uses interconnects that are shielded, it's best that the shield is connected to the ground at one end of the cable. I've also been told you can disconnect the entire ground at one end of an interconnect. Never tried it, but maybe someone here can comment on that.
