AIR1 v AIR2 v Spark

[Magagne]

I tried the ultimate and the most simple connection path. I strip down all possible noise variable that can affect streaming. It is by using RJ45 directly to the devialet, no router/switch, no network in the equation. Just a hardwire, static address, direct connection.

1- Took the IP address from Devialet (use static IP address mode instead of DHCP mode, 192.168.0.77).
2- Configure my MacMini with a static IP address IPv4, base on the same subnet of the Devialet IP (192.168.0.XY).
3- Plug my MacMini directly to the Devialet with RJ45 CAT6 cable, 4 feets long.
4- Last version of OSX version, last update, last Firmware.

I resume again, so NO router, NO switch, NO wifi (MacMini wifi was OFF too), NO network. Full hardwire, direct connection, MacMini + CAT6 + Devialet 120 that’s it. I cannot do more simple than that.

Start itunes, with DevialetAir, in ethernet mode. Well, after some time, with hires, same cracking/white noise crap, even if I adjust the buffer size.

Hypothesis: Is that can be possible that there is a bad batch of the network card from Devialet? That will explain why some user has problems, and some don’t?
