I also just got the gold cable bundled with an Equi=core 600. It's the first good power cable I've purchased so I can't compare with other after-market cables but it seems exceptionally well made. So much so that I just ordered two more from Walter, who is fantastic to deal with.
Underwood HiFi Cables
Was wondering if any of you folks have any thoughts on/experience with Underwood HiFi’s line of cables. I grabbed a pair of “gold series” interconnects with my new DAC, as Walter offered them at half price with my purchase. The website is pretty sparse on details regarding composition/geometry/specs, and all I have to compare them to are some garbage generic patch cables.
