I have not, but it looks interesting. I don't really buy that transmission line effects matter at audio frequencies for typical installations, so I would have used a thicker intermediate dielectric to achieve low capacitance as well as relatively low inductance rather than going for a low-Z cable with relatively high capacitance. That's a pretty hefty capacitive load, though probably in the mud as far as the amp and speaker are concerned... - Don

Don: Think you're right about the electrical properties and possible interactions. Years ago, had the speaker cables in and didn't like them between my cj amps and Martin-Logans. One thing I remember is that they were in my system, rolled off and congested. OTOH, one of my colleagues had good success with the speaker cables between his Modjeski amplifiers and smaller Genesis speakers.
Thanks Myles. We've all experienced that sort of thing... I think that's one reason there's so much debate about cables in particular. As I have noted elsewhere, the measurements don't mean anything if they are not done in the right environment. Interactions among components and cables aren't all that hard to measure, but it takes a lot of gear and knowledge most audiophiles do not have.
I spent a lot of time finding good cables to run from my old tube preamp to my amp, looking mainly for very low capacitance since the impedances were so high. In a SS system, I'd probably trade higher capacitance for lower inductance and resistance due to the much lower impedances (source and load).
It all has to play nice together to sound good... - Don

Yes and there are special instances where the cable's electrical properties are exceedingly important eg. matching the impedance of the head block in a R2R machine!
