News about AIR-crackling noise from Munich

[midi]

But my impression is, that the solution (at least for the Mac/OS) is far far away.

I never ever had a problem with streaming from MacPro, iTunes via AIR and ethernet (dedicated fixed IP or not). Alternatively, as suggested by Devialet, I run iTunes-PureMusic-firewire-Weiss-AES-EBU on my D800. In both configurations no noise, no crackling, no nothing. Let me say that I also use Dirac room correction but avoid any of the more fancy alternatives to iTunes such as Audirvana, etc. When I tried them in the past it was always a hassle besides of not playing gaplessly.

In my experience it helps very often to setup the OS anew once in a while (e.g. every 1 1/2 year) on a completely deleted HDD or SSD and also to install the applications from scratch. Even though this is a few hours work, it is worthwhile in terms of sonic, speed and practical behaviour of the Mac. Installing and uninstalling software accumulates bits and pieces of left-overs in the OS-library that should be removed.

I have different mac´s (and apple wlan routers) and with all this devices the same problem, so I have no hope that deleting and reinstalling everything is a solution. In addition I have still tried this with a brand new mac book, without any improvement. For me AIR is the problem. The only solution for me to avoid crackling noise is using a Mac via USB or a an Apple TV via optical or the Sonos Connect via Coax. But as I purchased the D120 I have done this under the aspect to use a wireless control with the possibility to stream high-res files. Both not possible with the other solutions. For the moment the Auralic Aries is a (expensive) solution, but then I have another device and I would depend on another software solution from Auralic and no multiroom solution.
