I've connected my Onkyo ND-S1 iPod dock to the 2310 via digital optical cable. I'm pleased with the sound, but understand that if I'd bought a Denon dock I could have enjoyed increased functionality by connecting a separate cable. I wonder if anybody is able to tell me what these additional features are and if there's any way of getting them with the Onkyo.
Thanks
