Speaker cables for Linn Kan I

Hi, I'm running both LS3/5a and Linn Kans with Kimber Monocle XL. With the LS3/5a the Kimber is a great choice in all ways. Not so much for the Kans. I think I can get more out of them with another cable choice, hopefully nothing like as expensive as the Kimber. I'm most interested in trying some budget or DIY stuff to find a better synergy. Less hardness in the mid and firmer bass with a leaner sound would be nice. Anybody's advice on a direction to go in would be most welcome, thanks.
