OK, some cables seem to enhance bass response and I hope you get some suggestions on that, but such a cable is not neutral. For my 2 cents, if you want more bass, look into spending on component upgrades and perhaps power cords--and check your speaker positioning. IMHO cables don't work as tone enhancers.
