I would have thought the source itself and the quality of its respective outputs would be a large factor. Devialet did claim in the past that AES/EBU was best for external sources. In theory AIR ought to be the optimum but I've never been that satisified with sound quality from AIR. I've used AES & SPDIF from the same source (a Moon MiND 180) and found AES very slightly better - a tiny bit sharper. My recent sources have all been USB and I haven't been dissatisified with any of them.
