Power Cable from wall to my conditioner?

Hello, I have dedicated house lines and PS Audio receptacles for my stereo system.  I use an Isotek Aquarius conditioner that came with Isotek's entry level power cord.  I would like to find a better power cord to serve my conditioner but something that won't break the budget. I want a cord that will not restrict electrical flow and deliver all the open power it can to my Isotek which, in turn, serves my entire system.  My components are:
Old Wadia 581(rarely use anymore)
deHavilland Ultraverve preamp
Bryston 14BSST power amp
Bluesound node 2i feeding a Chord Qutest DAC
Purist anniversary bi-wired cables feeding B&W 802 diamond speakers
The tubed deHavilland serves to "warm up" and give air to my systems overall sound (this is the sound I like).  I wonder, do I want a copper configured power cord for the Isotek, or a copper-silver or something else?  Any ideas.  I understand that many of you may think "you just have to listen and go from there"...of course that is the bottom line.  But my thinking is maybe some of you might have strong feelings about which way to go and could help narrow the search?  Thank you, Jim
