I ended up going with WireWorld Silver Eclipse 6. At 50 hours I feel that they are still burning in, but they are already a nice improvement over what I had. The sonic signature is neutral to maybe one tick cool. They are not bright. The upper end is clear without seeming tipped up. There is much greater detail coming through. Bass was flabby initially, but has gotten much tighter. I am hoping for tighter still.
Disclaimer: I also changed to Silver Eclipse 6 interconnects and Silver Electra 5^2 power cords at the same time. Thus, my comments go to the aggregate sound and not to just the speaker cables.
