Ethernet cable upgrade

[cereal killer]

Team,

I do believe that analog cables can make a difference in sound, but I am still at a loss why a network cable in an asynchronous set up would make the slightest difference.

Indeed when using Air the Devialet reconstructs the audio digital stream from asynchronous TCP/IP packets, so the timing (or jitter) of the packet as they travel over the ethernet cables should have absolutely zero impact on the sound.

Anybody with an explanation?

Cheers,
Bernard

Maybe the shielding used in the Cat7 and 8 types of cable prevent ingress of RFI/EMI, making for a blacker background?

No it wouldn't, theres no analog info, all is 1 & 0 as in digital format. if 100% packet data isn't delivered it simply wouldn't play. Digital signal really is on or off. Analog on the other hand can be manipulated should there be need.
