I recently had a home audition of Shunyata Sigma, Audience A24 SX, Clarus Crimson, and my Wireworld Silver Eclipse 7. I preferred the Clarus, followed very closely by Audience. In my system the Clarus provides the best detail without being forward, presents a wide and deep soundstage, and great front to back placement.
My interconnect cables are Audioquest Fire XLR and my power cords are Wireworld Silver Eclipse 7 with Platinum plugs. I recently compared Shunyata Sigma power cords to the Wireworld and decided to keep the Wireworld.
Cables are really a crapshoot and the only way to know what's best is to evaluate them in your own system. The problem is there are endless combinations and it's impossible to evaluate everything.
