Power cord replacement where first?

Upgrade all cords with Pangea and call it a day, for less money. I was very impressed.
Glad to hear things might get even better with a dedicated 20 amp line.

My experience: CDP:phono stage:power amp in that order. Smallest difference was with my pre-amp and power conditioner. I would do CDP first then integrated amp. Depending on what you're looking at, make sure you get a shielded cable for the CDP, not really needed for the int amp.

So I put it on the cd player. Definite improvements! Haven't pinpointed it yet, but music just sounds more.... "Right" definitly quiet or more quiet than stock. Listening is so much easier. Listening for many hours has become a much more common occurrence. I have not yet tried it on the amp and might do so for comparison, but I'm extremely pleased with the way things are sounding. And I paid $108 shipped for 6th, so I consider that a bargain. Thanks again everyone for the input

Every cord Line conditoner then Preamp.
