I have moved from Supra CAT 8 (good) to Wireworld Starlight 8 (better) to now Audioquest Vodka (best of the 3). Each step was an audible improvement, with the AQ Vodka a significant increase in quality from the Wireworld Starlight 8, which was very good.
I intend to try out the WW Platinum 8 when I can find a 10" used cable. I live in a spacious 1 BR apt. in NYC (by relative terms) and there are a a lot of cables stuffed behind components, router, etc. and some have to stretch. Neal
