Hum...ZYX with Tom Evans Groove Need suggestions

have you troubleshot the rest of your system? swap interconnects to see if the left side still has more hum. the ground from your tonearm should ground to the ground lug on the back of the groove. doublecheck all connections, from the catridge on up the chain.. etc. the cartridge/phono pre combo you have are top notch. there is an issue elsewhere, or you have a defective component.

as GMC noted having the power supply in the wrong place will increase the hum. i found that out my self when rearranging my rack. problem solved by moving it around for the quietest location. good luck and enjoy the music

Yes, I have tried different interconnects with different geometries, the slight hum remains. A fellow on a different forum recommended that I open up and add another ground to the Groove which I have done but it didn't improve. I will probably be moving the Groove out and away from my audio rack all together, I currently have the power supply of my mono blocks and preamp in close proximity. I have heard others with hum issues with the Groove, wonder if they ever got it figured out.

can you move your amps further away from the rack?
