++power cords with power conditioners?

PS Audio recommends not using a power cord with filtering with their Power Plants. Go to www.psaudio.com for more information. You can even download the owners manual for the P300 and P600. I have a P300 in my system and on the list for a P600. In my system, the power plant made more of an improvement than power cords or cable upgrades. Good luck.

No, I do not work for PS Audio. The original postings asked about power cords and the PS Audio P300. I just stated what PS Audio recommends about power cords with the Power Plants. I have after market cords through out my system. I did not say that power cords don't make a difference, I said in MY SYSTEM, the PS Audio made a bigger improvement then upgrades of cable or cords. As always, listen for yourself, many upgrades are system dependent. In my system, the Power Plant is an improvement, thats not saying it is for everyone.
