A lot of choices out there! However, I will cast my vote for Shunyata Research Sigma speaker cables. I am a big fan of Shunyata and have a loom, plus an Everest power conditioner. I highly recommend the Sigmas.
I have not heard these but they get a lot of rave review from consumers over at whatsbestforum.com: Albedo Monolith Reference cables. People say that once you hear them in your system, that is it. I am very happy with my Shunyata's so I am sticking with them, but something to check out.
