Thanks Steve,
I am currently using a Kimber Select 2020 0.75m BNC-BNC between offramp 4 and ARC DAC8. I have since read your advice that a1.5m cable is recommended. The same Kimber cable would be very expensive, so I am looking for alternatives that have equal or better performance, but more reasonable cost. I would be prepared to pay $500-$600.
cheers
