if the CI board would have reached it's full potential it would be a bad hardware design. I think it is not making full use of it's potiential because of the software.
A 400€ ifi Zen Stream is playing on a much higher level, connected to the Devialet via USB. And there are even better devices available.
For me the benefit of the CI board is that it provides a better clock to the other parts of the Devialet resulting in better SQ.

I tend to agree here. I use an Innuos Zenith Mk2 streamer into my 220 Pro CI and it sounds sublime, even streaming from Qobuz. Locally stored music in DSD format for well known albums are second to none.
