Hello Veovis,
I think that even the older internal DAC of the Moon i3.3 was beating some converters (I have personally tried V-Link 96 & SoTM 192), so I was wondering if the upgrade worth the money. As you say this is one of the best so far? I think that all of this kind of conversion, power supplies & S/PDIF cables when a "normal" USB converter is involved finally degrades the signal. Do you know if the new internal DAC has any kind of electrical isolation regarding USB?
