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
