Sorry dude, sometimes I mistake someone asking for instructions for someone asking for suggestions. Just trying to be helpful, no need to take offense.
Onemug and Metralla answered your question if you were looking for instructions.
If I were you I would get a dock that has the Apple licensed chip for digital out. The point is to get your rDAC doing the conversion and get some enjoyment out of it.
For that, Onemug's suggestions would do it. Another is the Onkyo ND-S1.
Another thing is to ask Arcam or the place you bought if from. Might save you from having to read our non-specific ramblings.
