I have a third gen 30 gig Ipod hooked up to my 990 thru a docking station via an RCA Y cable hooked up analog to AUX stereo inputs. Only problem is I cannot label that particular input so it reads AUX on the 990. I tried hooking the iPod directly but it works much better with the docking unit.

All my songs on the iPod were recorded off CD at at least 224k and though it is not CD quality, reference listening quality it is quite good for listening while working around the house, reading or when I have a group of people over. It is a nice addition to my system.
