I think it is time to make some things clearer. My approach was to replace a two box solution with a single box including web control. Primary source is the NAS. Källa was recommended, Källa is here.
Music is in the foreground and I have expectations of the reproduction. Musicality and presentation are my criteria. Now there are two streamers here. One has the slightly better presentation, the other is ahead in musicality.
Power range, as well as network settings of the Källa are set up according to the recommendation. Test of the network showed, without switch it plays better. Further changes to the network can only be realized with very high effort.
@matthias, a function only send or the like do not offer the WLAN repeater.
If I now follow ThomasOK's argumentation, Källa is not optimally configured, is therefore operated incorrectly. Spotiy might be an option, which the NDS can also handle. Although it is delivered over the same network, their stream is obviously better than self-ripped CDs. But, I'm not in a position to judge that.
Anyway, here are renewed recordings with recommended power configuration.
Källa - NDS - Sagatuns - Tundra stereo
