This is a really interesting thread. I hope we can keep the dialogue open-minded and reach some interesting conclusions.

My 2p here; I don't really know the differences between network protocols etc. so it is very informative to learn more about this.

I understand (just about) that there should be no real effect here when dealing with audio packets to ID40, MS600 etc.

However, I have also experienced a change in SQ from the ID40 when changing my network path AND location of core and store. I know it's not PSU changes but relevant to the discussion all the same.

To my ears (and I don't rule out tricks in my head):-

MD600 core/store in room #1 feeding the ID40 in room #2 through just 3 network wired switches sounded better than;

Core in room #1 calling from store in room #2 to ID40 in room #3. Core in this case was sat on the network via TP Link powerplugs and well within the bandwidth of the plugs.

Packets are packets - I understand. There should have been no difference - I understand.

My ears told me there was a difference - I do not understand.

As I say, I cannot rule out tricks in my head. But, I also suspect that there is more to network audio than we've currently understood.

Rgds,
