I appreciate the responses. I hadn't realized that there's no going back from an MP3; though now that I think about it, it's very reasonable. Given that all I have are MP3s right now (and I have lots of them), the DAC on Airport Express should be more than adequate, I should think? Or, perhaps even the DAC in my laptop via the headphone jack would be adequate?
Thanks again,
Matt
