strike that. when the empeg is out, it's now quiet, but...when it's in the dock, I get hard drive noise if the rca's are grounded to the barrel of the DC plug.

Can you repeat this, mark? If so, then you might need an interruptable ground in the next design: ground the rca's to the shield of the dc plug when the empeg isn't in there, but don't do so when the empeg is installed?
