Bbopman - The only thing that can change sound, if digital file is the same, is jitter (it was verified by Stereophile that Airport Express transmission is bit-perfect).
Music stored on the hard drive has not timing. Music is transferred to AE compressed (ALAC) in packets and buffered (few seconds buffer). Timinig is created by AE. I cannot imagine how playback program could change sound with wireless AE unless CD was ripped differently (Itunes does not rip bit-perfect).
