I previously demoed a pair of GH SX cables in my system courtesy of Mazz. They sounded better than my AQ cables so I purchased the latest ZX dot cable. I have to say when Steve(?) told me that these were even better I was skeptical only because it is salesmanship. Well I have to say my jaw dropped when I heard it. I didn't do a side by side with the SX but I believe there was a significant difference. I could never go back to my old AQ. Nexy stop is power cables. :drool:
