I talked to Chord about this issue as I do not use a Mac; apparently ASIO is not supported on iOS. The issue of dropouts is the source sending faulty data; when the DAC sees a fault in the DoP format I used to have a full mute, thus making the dropout obvious. However, I have fine tuned the treatment of faulty data, so that now a hard mute is not created, and you may hear a tiny tick when the source transmits faulty data. In practice it is very hard to detect now. But the treatment still means that DSD changes does not create clicks and pops. It took quite a lot of effort to mute when DSD changed, but to be tolerant of small errors in the data.
