I’ve not tried one Mark but isn’t it a bit of an overkill for a single Dac and source replay system?

My understanding is they may be useful for controlling jitter in multiple processing system such a recording studio by acting as a master clock for multiple slave clocks but most Dacs these days have accurate enough clocks for jitter to be negligible.
If the incoming data is buffered and stacked and clocked out to analogue conversion by the Dac clock rather than the source clock then isn't jitter in the incoming data stream is rectified at the buffer
If jitter in a two clock set up is a problem then wouldn’t it make mores sense to just get a better Dac with a more accurate clock?
Idk, maybe the above is only relevant to USB data transfer.

Intersting though.
