I'd try the AES connection. Try the Mogami Gold AES/EBU cable--I got one for about 43.00 from Musicians Friend. They have great Neutrik gold connectors, nice construction, very neutral, and are used by most recording studios as standard equipment. I found this sounds better as an interconnect between my BelCanto DAC3 and CD1 than a coax, which sounded really good too. But the balanced connection gives even more quiet background and image depth and detail.
