Anti Cables, I swear by them, amazing clarity and bass... Currently running the new Flex 4.2 , one of the best bargains in HiFi, blew away much more expensive cables I had before like Audience ...
I use Acoustic Zen for everything else, they make my favorite interconnects and power cords, I tried the Anti-Cables power cord and it was terrible compared to to my Acoustic Zen Krakatoas
I never tried the interconnects but I doubt they can compare to Acoustic Zen Absolute that I use, but I would try them someday
