Crazy Idea

Would it be possible to run an optical signal, say from an Apple Airport Express, to a D/A converter? Are there DA converters that take optical? Is the type of optical from the Airport Express usable? What is a good D/A converter? Thanks
lots of d/a converters take optical, at least toslink. I know nothing about airport express..or do you mean wireless? if so, I don't know Good luck
Yes, I run my Airport Express to the digital input of a receiver, and use it's DAC's with good results.
