I run from an AE to a Bel Canto DAC2. I use a simple glass cable I bought from monoprice.com. For my application, this works fine. The Bel Canto is great at jitter reduction. Your DAC3 is generations ahead of my DAC2 in jitter reduction, so I assume it will be even better than my setup.
Airport Express to DAC - Cable Suggestion
Can someone suggest a suitable cable to go from the Airport Express out to a DAC. If the DAC has USB, is this the best way or should I consider the optical out to the DAC's Toslink? Bel Canto DAC3. Thanks.
