For the record.  Devialet AIR buffers data and re-clocks in the amplifier itself. This will eliminate any jitter, as far as the Devialet's clock accuracy will allow.  Consider, you can set the AIR buffer to 5 seconds, play music, remove the Ethernet cable from the Devialet and the Devialet will continue playing music for 5 seconds.

Ok, I'll try to explain jitter in a computer and audio chain to my understanding. Correct me if I'm wrong.

First thump5 is right. Jitter is present on every signal path in a computer but the 'normal' programs don't care because they have a protocol to check if every bit that was sent was also received. Nothing is lost but sometimes the programs have to wait until another process/service that interferes with higher priority got its job done. In this scenario some bits/bytes may be delivered later/ealier than it was meant to be. But they just fit in as time is not important.

On the other hand time is one of the most important things when an audio signal is sent. It has to be a continuous stream. If some bits/bytes come before/after they were meant to arrive the 'tone (or part of it)' is extended over time. We recognise this as distortion/hiss/boomy sound...the tone is stretched...the 'S' in a singers voice becomes a 'SSSS' that's the hiss.

My understanding of AIR is that everything that reaches the AIR-Driver (the front door of AIR) is afterwards sorted and send jitterfree/timecorrect through every signalpath of the computer and the network until it reaches the front door of the Dxxx. Then it is converted back into a stream without a time correcting protocol and therefor is prone to jitter again.
The problem as I see it is the signal path from the HDD/SSD up to the front door of AIR. I don't think there is a jitterfree time dependent protocol that holds jitter off this signalpath. But once this jitter contaminated signal passes the front door of AIR the AIR-software takes it as an original signal. The induced jitter can not be seen by AIR.
This is the same with jitter contaminated recordings. Once you have the jitter on CD or in the file you have to live with it. You can't calculate or filter it out of the signal after the recording is done.

I think it's difficult to imagine the flood of bits/bytes all have to be in a correct time dependent order because it's so much data. Though our brain is very sensitive on the timeline when it comes to sounds. This may be related to our instincts to survive in ancient history...what was the topic of the thread again   .
