   This works but it is hardly obvious.  I created an aggregate device in   
   Audio MIDI Setup that contains both DACs.  I made the 192kHz DAC the   
   Clock source and set it to 192kHz.  I made the 96kHz DAC the output DAC.   
     I made the aggregate the output in Pure Music’s audio setup.   
      
   I am not a software guru so I’m only guessing but I think the 192kHz DAC   
   is telling Pure Music it is okay to send the audio aggregate a 192kHz   
   signal and that signal is being sent to the 96kHz DAC, which is capable   
   of playing 192kHz signals if you can get them to it.  I have searched   
   the internet and can find no explanation of how audio aggregates   
   actually work, so this is pure guess-work.
