Importance of power cable for Turntable?

I have a VPI Aries Scout and I hired a local dealer who also happens to be a real analog guru to make a house call to set it up properly.  He said the outboard power supply on my particular table was in no way in need of an expensive power cable.  Interconnects are the key and as for the expensive power cable? Better used elsewhere in the system. 

Power cord is an extension of the power supply not of the wall wires. Good well-matched cord will improve the performance of anything that has it. If you can't hear it something is wrong. At higher level one can clearly hear that different cords have different sonic signatures with the same component, not necessarily better or worse. Also, some cords do tend to work better with source components or/and preamp and others with power amps and conditioners/regenerators. My Nottingham turntable's motor has captured cord so I can't upgrade it. Motor controller is a different thing and no substitute for cords, in fact it will benefit from good power cord too.
Anyway, when it comes to turntables I don't know what doesn't matter, it is a very sensitive thing, like it or not or both.

It makes absolutely no difference what so ever. Use whatever comes with the table and spend your money on something more important like a Pizza.

Hi,
TT power supply (especially if it is an outboard one) will most likely benefit from a better quality mains cable and material, so yes it sounds better in many ways.

Why only power cord, just do like this person.
