Importance of power cable for Turntable?


Just purchased a Gryphon Diablo 300 integrated with the optional phono stage and DAC module.  I purchased AudioQuest Hurricanes for both the amp and my digital source.  How important would it be to do the same for a high end turntable (which I don’t have just yet)?  Would an AudioQuest Hurricane Source be a good choice for a high end turntable as well? Or is it even needed?  I do notice subtle improvements with my amp and digital source.

Thanks

Actually turntable power supplies are one of the most sensitive areas in an entire system for power cord upgrades.  I just recently helped a local audiophile change the cord running from his VPI SDS to his HRX (so this is the one after the voltage has been smoothed and cleaned) the effect was not subtle. I get the same from changes to the cord into my EAR table supply.

If/when you get a table you can simply swap the cord from your digital source and listen, you may well be surprised!
The motor is a source of EMI which can affect  components sharing the same AC line or by direct radiation from the motor or its power cord. So if a cord provides good shielding and/or has built in filtering, its possible you’d benefit.
 
Thanks All.  I had heard the first argument already (from Elizabeth) but was also wondering about “pollution” of the AC line caused by the motor, with the AC line being the same line my amp is plugged into.  Unfortunately my amp and eventual turntable when I get it will be plugged into the same AC circuit in my house.

I wonder, would something like a Furman 8D be better than a power cord upgrade for the turntable......  essentially blocking the noise from the motor from entering the AC circuit.  And would cost way less than the PC upgrade....


While all this thinking about noise from/to the table may be true (or may be better addressed by other steps as the OP suggests) my experience is that even when the AC is treated (as in my system) by multiple levels of filtering well before the power cord to the table it still is the case that changing the power cord to the table adds benefits. The effect is similar to a good power cord on an amp -- more stability and attack, more ease as the table is subject to wide dynamic swings, a crisper presentation etc.

All of this is icing on the cake in an optimized system but if that's where you are heading, and you have a power cord handy, do try one -- the effects are likely to be additive to whatever else you are doing (and that's before getting into the benefits of footers and other vibration control effects on the TT PSU as well ...)

Of course I may well be totally lost in tweakery woo land ... but that's the territory we're operating in now
