Actually the Anti-Cable website basically seems to suggest what Sean says: that twisting the runs may ameliorate top end roll-off by lowering total inductance. I was apparently misremembering when I implied that Speltz's site suggests twisting will do the same for bass response.
I tried researching further on the web, to locate whatever reference I was remembering about twisting, inductance and bass response, but couldn't find it again. I did, however, find seemingly contradictory claims surrounding this topic -- and that was looking mostly at independent technical writings and those posted on manufacturer's websites, not those of non-technical audiophiles (such as myself) in forums such as this. (There seems to be similar disagreement over the importance of characteristic impedance.)
So it's hard to know what to make of this. I guess the best thing to do is listen and compare, twisted vs. untwisted. The one time I tried separate-lead speaker cables, I twisted them together as recommended by that manufacturer (the cables sounded rolled-off in the treble and bass-heavy, so I didn't buy them, but I also didn't try them untwisted to compare). A lot of the online papers I read were written by technophiles whose larger agenda was often that fancy audiophile cabling is snakeoil and a ripoff, and who also claim inaudibility for different variables which I personally believe I have heard. Whereas of course the manufacturer sites are mainly trying to sell a product.
As the for the effect of dielectric pigment, given the arguments presented above, why should gray 'sound better' than black? Or red 'sound worse' than clear or white? In any case, it seems to me that the whole point of the dielectric in Anti-Cables is that it's as minimal as possible, in which case so should be the 'audibility' of its pigment.
