JA - So much to learn, so little time.
Rob - Your 2.7 wire was a New Thiel addition or experiment. They hired first-rate designers and engineers, so I trust it was very well considered and chosen. Their failure was at the executive, not technical level. We here did a parallel vs twisted exploration and seemed to all prefer the parallel, including myself. I can’t go down that route because I lack the knowledge to crack the code. I know enough to know that there are many factors including radio frequency interference and capacitive coupling with stray fields that are much more problematic with parallel runs and solved by twisted runs. Note that your stranded wire quite likely has the the stranding twisted to minimize coupling. So it would be a hybrid, quite different than parallel runs of solid wire.
Regarding your Cardas wire - that sounds optimum to me. All insulations, including Thiel’s teflon, introduce dielectric effects. Varnish is considered optimum. Also cotton and other cellulitic fibers are considered optimum - better than any of the plastics including teflon. AntiCables has built a respected product around varnish only. Morrow uses varnished strands in cotton. I find both those produces very satisfying. I don’t personally know Cardas’ results, but they have a very good reputation and I say he’s on an optimum path with what you describe.
The Cardas wire you describe could be ganged ie single pair for tweeter (or double for star quad), and ganged as double or triple for the other drivers. Need can be predicted via crossover analysis of the relative current capacity of the network - gauge of series inductors and parallel paths to ground. I would be glad to offer an opinion via PM.
