build the cables , I have and while I am not one to say a thing is better sounding than another (way too subjective) ,I can say the cable has surprisingly good sound for the price.
Plus the look is too coool
Use RCA plugs with strain releifs AND cover it with heat shrink for extra strength . Use red and black for L/R color coding or color coded plugs.
twist two wire together and use clear plastic tubing (from pet store , the pump tubing used for aquariums).Still looks pretty cool but is a more "conventional" design.Just be sure to mark one wire at BOTH ends or you will have to use an ohmmeter to differentiate between the two leads (hot and ground)
Also it would not hurt to try the "risch" coax cables.Radio Shack carries the equivelent Beldon cables by the foot (actual Belden)
And finally - build some CAT-5 cables in the manner of Kimber Kable.
I use all of the above in combination with commercial cables.What sounds marginal in one application may sound killer (again ,use YOUR ears) in another.Short runs may not need shielding , long runs it may be essential.Match the cable to the application.
Build them if only for the enjoyment of "I did this".You will not be sorry
