speaker cable placement/arrangement

Hi A-goners,

I searched the arhives and couldn't find any answer to my quesiton: what is the best way to place, arrange, organize, etc. speaker cables. Should they be as straight as possible from the amp to the speakers? Should any curves or bends be at right angles or any other preferable configuration? I'll probably be buying 8 or 9 feet runs, but I could get by with 6 feet runs. What's the best way to place them?

Thanks in advance,
russ
