Purchase European 220 power cords and power conditioners in the U.S.

Most European suppliers will ship to the US.  Order what you need from over there?  

why do you need cables?

Ask your Puritan Audio dealer. They can supply their conditioners with either Schuko or UK or North American outlets. Same with power cords. These will be special order of course you'll pay up front.

You probably should be looking for a switch mode power supply similar to what is supplied with just about every portable device that consumers buy these days. They work with any input voltage from 100V - 240V anywhere in the world and all that is required is the correct snap-on AC receptacle that they all come with for whatever country you're using it in. I would assume by perusing the internet you might find similar heavy duty power supplies that provide the necessary power for current hungry hifi components.

A caution on AliExpress. High end name brand cables there are counterfeit. If the price is a fraction of typical... it is not real.
