Importance of power cable for Turntable?

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....

Wow!  Okay I’m hoping not going to quite that crazy with power mgmt lol!

Have to point out the slight irony in all of your power mgmt lengths you have taken but use a stock cord to the turntable!  Probably makes sense though.

One more thing that may or may not be nonsense is that I’ve heard that the Gryphon’s power regulation is “so good” and resilient to noise that differences in high end power cords with this brand is not as large as with other amplifier brands.

Agree with Elizabeth, when I said I hear subtle improvements it is easily discernible for me but not jaw-droppingly so.  And it is worth the cost for this subtle improvement in some of the background detail.  One point is that my Hurricane is only about 25% broken in, so maybe more changes will become apparent.

Regarding the Diablo itself - now that is not a subtle improvement over other equipment I tested, and I will succumb to superlatives to describe the differences I hear...  And I am not of the opinion that at a certain level everything sounds great.  Of all the amps I tested the Diablo is the only one that had no sonic qualities (on certain music) that I found unpleasant in some way. 

Back to power management, I’m quickly realizing this is not a simple question that is specific to the turntable.  I need to figure out a system wide approach that doesn’t break the bank.  For example, adding a conditioner is one thing, but then there is to cord to the conditioner - things can get crazy expensive(er) fast....  I am not looking to get every last bit of performance possible but I’ll want to do something that gets me most of the way.  Perhaps I need to start a thread in a different category on a system approach to power mgmt.  Really just looking for a general direction on approach.  There are lots of theories and the brand marketing doesn’t help as it seems to not really communicate anything beyond marketing gibberish.

I would hazard a guess that system resolving power is one of many variables that could bottleneck the performance of a power cable or make differences in cords less noticeable.  I’d think it also depends on how noisy an environment is, how clean the AC input power is, and also how good the regulators are in the components that the cords are connected to.  In a hypothetical (and probably not realistic scenario), if you have a highly resolving system, clean power, no material EMI to speak of, and high quality regulation built into the gear, maybe you wouldn’t notice differences between cords.  Some very high end gear comes with power regulation in a separate chassis.  Is it possible that such components, if implemented right, at least partially negate the effects between a lower end and higher end cord?
