My apologies for the simple question… What is the signal actually being measured for the “Toslink digital out” signal? Is it the Toslink being fed through a reference DAC, or something else? It sure doesn’t look like a a Toslink signal itself, but like an audio signal.WiiM Mini Measurements
My first tests were using Aiplay 2.0 as initiated by my Roon player. As usual, Airplay itself becomes the bottleneck as we see with Toslink digital out:
If it is a reference DAC, which one please? Doesn’t that show more about the ability of the DAC to tolerate a digital signal’s characteristics, rather than the quality of the digital signal itself?
Or am I just reading this wrong.
