inexpensive dock for iPhone 4 with digital out


does such a thing exist? 100 dollars or less? I want to run a digital coax cable to my W4S DAC-1 and listen to MOG radio through it. Thanks.

pure i-20 is 99 dollars. check their site for applicability. i use one with a 160g and a 80 classic and it sounds very good. doesn't work with the 30g classic but might with the new iphones.
I second the suggestion for the Pure i-20. The best $99 I have ever spent on audio. An amazing product for the $$.
Do you know if it accommodates an iPhone 4? I notice it has a built in DAC. Is it possible to take the digital stream direct, bypassing the onboard DAC? BTW, have you tried the onboard DAC? If so, how does it sound? (just curious)
