Power cord for PurePower2000

I have a PurePower 1050 and thought that a aftermarket cord wouldn't make a difference. To my surpise all the cords I tried sounded different, even thou it regenerates and has a battery.
All the components connected will benefit, IMHO.

Huh. Interesting. I will have to tell my friend this. Thanks.

My question is about cable connected from wall socket to PurePower2000.
Other cables make really huge difference!
But wall cable not!
Is any expirience exactly with PurePower2000?

No experience with the 2000 but I had the Purepower 700 and power cords from the wall to the unit did make a difference even thought intuitively it would seem not to matter.

Murataltuev, if you are referring to me, I am talking about wall to unit cord.
