The audience Au24 is suppose to be great(or so more then a few have told me) for the money, however another real sleeper that has been getting a lot of good press is the Xindak speaker cables
http://www.stereotimes.comto read a review about the Xindak cables. I have been dissapointed with Zu's speaker cables, though that doesn't mean you will not like them. Asking what cable is "right" for me is an impossible question to answer, no one has heard them all and NO one hears them like you do. Most of the companies offer an in home trial so that is going to be your best bet.
The other option is with audiogon buy them used and try them to find which one you like the best and sell the others, you will only lose shipping. The used market on cables doesn't take a big hit, after the initial loss. The benefit of this is most of the cables will be broke in so it will only take a few days for them to settle and give you an accurate impression of how they sound.
