Never having a subwoofer-specific cable, I can't adivse on that. All I know is I like the way my system sounds with the AG-O ic's feeding my power amp. I have used Synergistic Research Kalidescope for that purpose as well, and experienced no difference in performance that I could discern.
Subwoofer mavens may be able to better advise you about dedicated sub cables.
