Sorry to ask a question that's not on the original topic, but since Steve brought it up, FWIW, John Atkinson measured the jitter level of the Airport Express' digital output to be 258ps, which in absolute terms is not high.

Steve, in at least one of your past posts, you've said that you do not use jitter measuring equipment, so how can you conclude that the AE has high jitter and that jitter is the reason why it didn't sound good to you? I'm not saying that you didn't hear *something* that you found to be wrong with the AE, but I am just doubting that jitter was the reason behind it.
