Black Sand Cable Power Cords How Good?


How good are the Black Sand Cable power cords? I want to upgrade my stock power cords on my integrated amp and cd player. I have been reading some very positive comments on these cords. I would appreciate any comments from current and previous owners. Budget around three to five hundred for each cord. Thanks.

I love my Carbon Editions AC cables from John. Amazing build quality and unbelievable customer service. Kudos to John @ Black Sand Audio. 

Since I received the AC cables, I've been thinking about asking John to make some interconnects and speaker cables for me. It would be nice to have a matching system. 

I'm currently using Morrow Audio 5-series for my interconnects and speaker cables. Has anyone had the chance to demo Black Sand Audio cables against Morrow Audio? I'm looking for best bang for the buck. 

Any input would be greatly appreciated.
