Metralla, yes the mini plugs into the headphone jack. As I said before I am using a Cardas cable now that was made for the iPod but also had excellent results with the Kimber Kable as well.
I only brought this up because the poster of this thread says he does not want to get a DAC with the Wadia. It is my understanding that without accessing the digital feed via a DAC first then there is really no need for this docking station. I just got a great deal here on Audiogon for the Wadia and a 160 gig iPod and I am looking at the Benchmark, Bryston, PS Audio line of DACs to complete my set up.
Noshortcuts, in the Oct. 2008 issue of Stereophile Wes Phillips states in his review of the 170i and I quote "if your going to listen solely through its analog outputs, you could buy an iPod classic AND dinner for two with $330 you save by buying a bog-standard iPod docking cradle. The digital output is the real deal." My point is the same. No DAC? Why bother.
