Upgraded power cables- Who's on First?

It all depends on what sounds best to you. I started at the conditioner. Then the Pre, Phono Pre, CDP. There are excellent power supplies in a lot of gear. With that said. You wouldn't get the best results using an upgraded cord on those units verses other components with a lesser grade power supply. My experience anyway ...........

So, how do you know which gear has a good power supply?

What? (2nd base)

How are we supposed to help if we don't know what pc's you have on hand to deal with now?

If you don't feel like moving your pc's around to find out which sounds best to you, then whereever you have them now is best.

For me to say put your brand X on this and brand Z on that, and not even knowing which one is which leaves me thinking...

'I don't know'.... 3rd base!

So we don't have to be psychics tell us what pcs you have and a bit more of your audio affair.

Why? (center field) ...There's more to it.

RE PS:
cost of the item will tell you something about the power supply in a piece.... something, but not everything. Some say the more effect a conditioner has on a thihng the less effective or robust is that items' power sup.
