Line conditioner for turntable,

I believe that both Walker and VPI make them available. Also, Origin Live has a DC motor kit that can be used in many different turntables. My TT is battery powered with a DC motor, and I found it gives a very good sound.

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

PS Audio power plants are, at least at face value, capable of speed control.
