My first thought having had similar "drop out" issues (in my case high volume clicks) when playing hi-res files in my Vivaldi stack is to wonder if its a DCS issue not anything to do with the clock.
Do you get the same issues when you play the files without the clock? I.e. using the inbuilt DCS clocking?
In my case no matter what I did I could not get rid of this issue, clearly there's something going on in the hand off between tracks that causes a drop and reconnection in the entire chain and it could be that the dropped Mutec clock is a symptom not the cause
ps love the Mutec clock solutions -- I use the Ref 10 master clock to drive my Vivaldi clock
