I have the Snake River Boomslang AES cable between my Jay's cdt2-mk3 and Gustard A26. Could not be more pleased. It took over 200 hours to burn-in, which they do for you, and after an additional 50 hours it actually sounds better than the I2s Tubulus Concentus cable I had. More natural, more rounded, more punch and not lacking in treble accuracy. The packaging is first class, but that's just an added benefit.
