I have (for my iPod classic, so check compatibility) a Denon ASD-11R dock for my 1909. The interface is terrible, it takes an age to find any tracks. I replaced the standard RCA cables with Chord Crimson which made it sound a lot better.
In any case, it's an expensive solution - altoghether about £110. I also have a Russ Andrews GQ-24 and think it's the better sounding option (but I lose out on charging).
