Kimber, Audioquest, Wireworld

I have made a significant change in my system by going to an integrated amplifier, the Luxman 550 A II. The rest of my system consists of the Harbeth M30 speakers, the Wavelength Audio Cosecant V3 Dac and a 2010 Mac Mini as a transport. Since I only need one pair of interconnects, I would like to move up the food chain from my existing Wireworld Eclipse 6 ic's. Here are the interconnects that I am considering:

Kimber 1036
Audioquest Sky
Wireworld Gold Eclipse 6

Does anyone have any experience with these cables in a system that is comparable to mine. Thanks
