repetitive clicking noises after a couple of hours of use

[Coffee_fan]

I also had a click/cracking sound coming from the left speaker (Triangle Delta's) when I first had my 200 last year. It was not loud, but nevertheless annoying ro say the least, and yes...I was running 'Air'!

Didn't happen all the time, but just like a recurring mouth ulcer, when it comes back, you know immediately what it is...and swear a bit!

I switched from Air to USB and the problem vaporised! So I would suggest trying a different method of connection (AES, USB, Ethernet etc) and see if this resolves before doing much else...
I don't use Air any more (sadly)!

Good luck...

Thanks, I switched for now to sourcing Tidal via the sonos-connect, which is ok for my current needs. Long term I will look into hooking up USB as I figure the Devialet should be asynchronous USB and would guarantee that timing and jitter are kept in check.
