Power cord feeding a power conditioner/regenerator

I am waiting for my Purepower APS 3000 to be delivered; it comes (it's the european version; I am from Italy) with a stock power cord with 20A IEC, so I can't use my power cords (Cardas Golden Reference) to evaluate how do they work on the power regenerator in comparison to the stock one.

I should buy a new cable with 20A IEC, or do it by myself buying a piece of a brand cable and the right connectors (Furutech, Oyaide, Wattgate).

Any experience, before I make an useless buy?

Thanks,

Emanuele
