What is an excellent power cable?


Looking for a high quality power cable. Anyone recommend anything? Also, is a quality power distributor important as well?

Look at Zu Audio A/C Mission or Birth cables.  I have replaced all A/C cables in my system with Zu Audio Mission cables.  Exceptionally well constructed and was an amazing overall improvement to my Pass and PS Audio stocked system !   Save some $$$'s and try them out .  ( Save even more by getting them through bids on eBay direct from Zu !!! ) 
Some older Shunyata's (Diamondback, Copperhead) have come down in used price to new-Pangea levels.
