I am use RS150  

my setup is 

USB out external DAC  , sample frequency set original ,  DoP out 

when I  change the song for FLAC file  I hear loud  SPARK noise very annoying  but DSF file seem not so loud   I further test when play the music in ssd then change to internet radio or airplay  I also hear loud  spark noise 

 use internal DAC didn’t have  I think mainly is happen  in USB out  

can you improve in USB out also add a fix volume function thanks
