Digital Cable Recommendation

I have over the last couple of years audtioned over six different companies single ended digital cables. The best I heard under $500.00 was the Acoustic Zen MC=Zen. To better it in my system I went to a Artistic Audio Vacuum reference that retails for $1600.00. So based both on cost and performance the Acoustic Zen cable is a real gem. One can be gotten used for around $200.00 to $250.00 here on the Gon.
