Herron VTPH-2 power cord

Hello. I have this phono stage, and absolutely love it. I would like to know if anyone is using an upgraded powercord on the Herron VTPH-2. If so, what kind of power cord are you using, and what effects have you observed as a result of changing the power cord?

Thank you very much for your thoughts.

Thanks Davt. Did you compare it to the stock cord?
When I had a VTPH-2 I used the Audience PowerChord SE with very good results. I use this same power chord on all the Herron, phono, pre and power amps.
No problem Dodgealum. Thanks for responding.
I'm using Empirical Design power cords throughout my system, including on my VTPH-2. I never compared with the stock cord or any other so this is a pretty useless recommendation--sorry!
