Mike, I am not a technical person and can't judge the design from this point of view. You can talk to Jim Aud of Purist Audio, he replies quickly, and ask him any questions. He is a former NASA engineer specializing in underwater signal transmission and he has been making cables for over 30 years. Aqueous fluid cable was his original cable. You can also talk to Audiogon member albertporter who is now Purist dealer as well. He personally has been using these cables from the very beginning of their existence, though he always has top of the line.
As for the sound, I'll spare you all the audiophile jargon, they are exquisite sophisticated cables with incredible soundstage. They do nothing wrong and almost everything right.
I would not rush with buying expensive power cord for Luxman. First, I would get tonearm cable and speaker cables and would listen for a few weeks or month with either stock Luxman cord or, say, $200 Audio Art Classic cord. 300 hours of burn in time for Purist, less for Audio Art. Then you could decide where to go next. It would also to a degree depend on how much electrical work on your house wiring you were going to do. But if you want to get everything at the same time and everything new, that's more difficult and possibly more expensive. Getting cabling perfectly right is tough even with unlimited budget.
