PC upgrade for Rega Aria?

@jazztherapist - I have had good results upgrading the power cable to my Simaudio Moon LP5.3 phono stage, which looks to be of a similar level of performance to the Aria.

However - to get any really discernible benefit I did have to use a very good quality power cable.

I have found that power cords make more of a difference when attached to more modestly price components.

In my case the Moon is in the middle of my component price/quality structure.

My amp, the most expensive component,  provided the least improvements in sound quality and my Bluesound Node2, being the lease expensive components, provided the biggest improvements

I would take a look at Nordost offerings for commercially available products.

If you are into DIY I would take a look at this PC

It is one of the best power cables I have ever used and I have found it provides improvements over many commercially available products  significantly higher in price

Good luck with your quest - Steve

Back when I was using a PS Audio Nuwave Phono I used an AQ NRG5 that I had lying around. Sounded pretty good I would recommend a budget cord first. 

Thanks, stereo5, that's helpful. What was the sonic upshot of your PC? What did you notice?

For my VPI Prime, I purchased an Audio Art AC3 power cord.  I purchased the one with the Watt Gate connectors for 150.00 but you can spend a little more for some different Furutech connectors.
