Couple questions: The signal coming out of the airport express is analog or digital? I was trying to stream iTunes via WiFi, to the a.e. then connect the airport express to my DAC then with RCA's to the pre-amp and 2 channel stereo. If the signal coming out of the a.e. is analog then I guess there is no need running through the DAC again, correct? If the signal is digital, what type of cable do I need to get to the DAC, a.e is analog/optical audio jack and input on the DAC is Toslink??? Im getting mixed answers and I'm confused at this point. Thanks, newb RonW.
