best budget audio cable IS digital !!!
Well it is in my opinion now, seems like a lot of people have been using coax constructed cable for anologue audio for years ie RCA plugged coax cable in pairs.
Look at NVA cables, the sound cord is a braided coax, the sound pipes are solid tube coax, ( have tried them )
This is REALLY great cable between your CD and amp and guess who it's from !!! ...........
