Lots of recommendations here. It is all very system-dependable. I would add Zu Audio cables to the list. I prefer them to Cardas, Cord, Transparent and Wireworld. They are very friendly and have a great no-questions-asked 60-days return policy.
Don't underestimate power cables, Shunyata is quite special here. Avoid cheap/budget aftermarket power cables, they are mostly marketing exercise, at least I have never encountered a good cheap power cord, that was worth the money. Fun starts when you splash a bit of your hard earned cash.))
