I think Gunbei's on point. If your looking for something other than a very subtle change, cabling should not be your first choice - get an equalizer or get rid of the component causing your problem. :-) Changes in cabling can effect tonal issues, such as bright or rolled off, but optimally it should be used just allow your componets to be heard at their best - it will rarely change a system's basic presentation, such as forward or recessed.
FWIW sources, preamps, amps and speakers, individually or collectively can produce an "up front" or very "laid back" presentation" and if changing the presentation is your goal your should consider an equipment change. Less frustrating and cheaper in the long run.
