Looked long time for a specific cable (black/green/orange)to logitech z-5500. I was told the only thing for me to do is to buy 3x3.5mm male to male plugs, strinkwrap and paint them the colors. Was wondering if I will be better off just buy a coax or optical cable. I have onboard sound and a SPDIF output in my pc and will it be better sound than the analog plugs. Thanks!
