BdGregory, Where do you get your AC power for all the gear? Is it coming from more than one wall socket? Is the system AC grounded at more than one socket? If so, the simplest thing to try first is to lift the grounds of all but one component, preamp is best choice to leave grounded with a 3-prong plug, since everything else is connected to the preamp. To lift the grounds of the other components, you may have to resort to "cheater plugs" available at any hardware store. A small difference in AC ground potential between one wall socket and another can result in low level hum. If this strategy does not help, there are more complex rituals that may do so. like lifting the ground wire from the turntable to the preamp, if it is currently attached to the preamp OR attaching the ground wire to the preamp, if it is currently free. As others have intimated, regardless of the cost of your system, you don't have to live with hum.
