If you have an AC synchronous motor driving your table, I highly recommend the VPI SDS (Synchronous Drive System). Go on VPI's website for a detailed description of what this unit does (it does more than just condition your power). I have one and am keeping it around until something better comes around. VPI also has a PLC conditioner - less costly - for turntables (again, I believe only for AC synchronous motors).
Good luck
