speaker cable

Can someone elaborate on Waldhorners comment on the electrical properties/cause and effect of cables. Can I search for a specific effect based on cable specs? i.e. if I want more-extended highs, can I narrow my search based on certain range of capacitance? I'd have more confidence selecting cables if I knew some general guidelines based in fact rather than hype and pretty colors. Audioquest does have a rather lengthy article regarding the technical properties of it's designs, but I didn't see any actual comparisons between "the specs" and "what we hear". Just links would be fine, I'm sure this topic could fill pages. Thanks
