Hmm, not to sure about that. It is digital data but it would not really be an I2S connection as it is the DSD data that is being tapped into from the Denon not PCM based data. Unfortunately all my notes and such are back in IL so I will not have access to them until late next week. Im pretty sure Russ' ghetto connection using alligator clips was quite a bit longer than 6 inches, but then again I am male.
