used to think that DAC doenst change sound quality

I was the one who thought DACs dont change meaningful amoung of sound quality changes But after upgrading from 70 dollar dac(fiio btr13) into 250dollar dac (ifi xcan), i realized that the sound change from DACs is indeed great!! Im not joking Its so obvious If your iem is over 200dollars and your dac is 50 dollars i recommend you to upgrade your dac
