Try to find a used Kubala Sosna Fascination power cable.These frequently appear at around $300 and make heck of a value (mainly for sources and preamps).
Value Power Cords- LessLoss or Triode Wire Labs?
I'm trying to gradually upgrade my system with some new /used power cords in the $400-$500 range. LessLoss and Triode Wire Labs cords seem to get great reviews. Has anyone tried them both and have any thoughts on either? Also other possible suggestions in this price range? Thanks for any help
