Changing power conditioner stock power cord

I could easily tell the difference between power cords I tried from Shunyata Hydra to the wall.

I completely agree with John on this. Change will happen, but is it for the better or worst, it's only for you to decide. You will have to try it.
Is you Exact Power a conditioner or a re-generator?

Narrod, very good comment. Do you have closed captioning turned on when you watch TV?

Audphile1: The Exact Power is a regenerator of sorts (it doesn't regenerate the entire AC waveform, but more efficiently compares it against a fixed internal reference using a sub-cycle feedforward technique and then compensates for distortions and voltage deviations by actively regenerating whatever's required to make the summed output correct, which is feasible because the desired output is constant).

Zaikesman, Exact Power makes 4 models. Actually one of them is a filter, model is called "UltraPure".
Which one are we talking about here?

Audphile1, I'm sure your system sounds wonderful. I don't feel a need to insult you.

Audphile1: Yes, only the EP15A model is the regenerator. The others are balanced isolation transformers, some with filters, intended mainly to be used in conjunction with the 15A.
