Interconnect Help

Anyone know of an interconnect that brings out the highs or would help make guitars more prominent? I really like the way my system sounds, but it is a tad recessed in the treble area, not annoyingly so but enough I notice at times. So I am wanting a little better treble extension but also don't want the dry etched sound either. Anyway,if any recommentation under 500.00 (only need 1.5 feet or so) I would appreciate it.
