Curious about Wireworld's offerings, especially those with OCC wire---how would you rate their better Gold and Silver Eclipse 7's? I have been using Transparent Reference XLR interconnects and speaker cables, all bought new in 2004. Are they at the end of their best service life, and would the Wireworld 7's be an improvement? I have ARC 210 (250 upgrade) monobocks into Maggie 3.6Rs, Wadia 861 SE GNSC directly into ARCs. Thanks for your opinions.
