Have no clue what Kelavin is about … even after a Google search. If you want to improve your digital sound you need to attack jitter first and then EM noise in your system. It’s not as straight forward as adding a new more expensive DAC
Digital enhancement
These from Kevalin audio remove distortions and add clarity , but after seeing the cost ,I said just buy into a much higher quality dac with excellent filtering and FPGA ,buffering , and filtering , like the top Denafrips 12 th anniversary Terminator dacs, or Holosprings May dacs , dacs that beat dacs at 2x their $5k+ price point .
they May work but waaay to much $$ their top effort almost $5 k
