I am using an Audio Sensibility SM Impact SE between DAC and preamp and a Canare SM DA 202 AESEBU between CD transport and DAC. I prefer this combination to single runs.
I find that the single AESEBU and analog XLR cables sound somewhat anemic in comparison, not as full bodied or dimensional.
I have a
Canare SM L-4E5C STAR QUAD, but am skittish about using it between a 1200AS amp and the preamp.
