Midrange heavy speaker cables, any recommendations?

It's fair to say that most all of my components are of good quality, are properly isolated and have a quite neutral personality. However my newer loudspeakers are a little on the bright side compared to my previous Dynaudios; and rather than swapping out components that have served me well I've changed speaker cables twice in an attempt to restrain the smoothly accurate, but somewhat abundant, top end. Rather than continuing cable experimentation I thought I'd throw the matter out there and get some feedback from my brothers out there the HiFi cosmos.

Any recommendations for reasonably priced (under $500) cables that have a more prominent midrange without compromising transparency and top end performance?
