Digital out : Yamaha wxc50, skysong , Douk U2 - soundreview.

No the Yamaha will not do that. I still think you are chasing explanations for improperly tested impressions.

Hmm… then the fault is in the Yamaha wxc50 that in AirPlay mode, both as ”player” and as ” pre amp” modifies the sampling frequency to 48 kHz ? Thats bad if its true.

Unfortunately…
WXC-50 will follow the source signal in Player mode for all the inputs except AirPlay.

I think that we have already discussed this here.

3. Douk audio U2 - a chinese USB bridge with xu208 and three different clocks , very small and neat.

I might be wrong, but as I understand it, the Douk Audio U2 has no internal clocks, but the Door Audio U2 Pro does have three internal clocks (you can also choose higher-end clocks, quadrupling the price from ~$50 to >$200, if you order from eBay/aliexpress).

The Douk U2 ( not PRO) has three different clocks, on the left side x1,x2, x3- one for each sample frequency.
