Mike, When you use network (wireless or not) music is delivered in packets without timing and timing is recreated by network device. Computer type or speed, amount of memory, program used for playback, type of hard disk, storage format etc. don't matter since they affect only jitter and timing was not supplied (unless playback program processes data, like upsampling). That's the beauty of it. Sometimes S/Pdif clock recreated on receiver side (N50) is less than perfect (jittery) and requires extra reclocker (or asynchronous upsampling DAC that does reclocking like my Benchmark DAC1) but at least you can forget all computer problems including noise (that tends to couple with direct connection or close proximity).
