if did a/b testing between pc internal dac and and meizu dac plugged in the pc but i did not do a/b testing between meizu in phone vs meizu in pc, i will do, thanks.
comparing meizu hifi pro on macbook white (2009) and on sony xz premium (2017), meizu sounds similar in both device but i notice my regular listening level is 55% when plugged in macbook vs 45% when plugged in sony phone, so volume management is different on different platforms.
my macbook internal dac listening level is 25% so meizu in low gain mode on my 43 ohms iem delivers 2x less power than my macbook internal dac, no big deal as it gives me finer volume control because there are only 16 steps on mac volume slider (still i don't have access to meizu 100 steps on mac, is there a utility/driver i can install on mac os to get 100 steps volume control ?)
meizu compared to macbook internal dac: meizu has more bass and voices are less nasal, soundstage is more centered and closer so sounstage is smaller on meizu (not night and day difference that will let you tell which one is which when listening from scratch (as when i pick my spring1 vs zs10 pro) but still noticeable in a/b testing, so in conclusion i would not really recommend to spend $40 on meizu pro when your device still has 3.5mm audio jack, invest these $40 in a better iem, it will be more noticeable)
meizu vs sony xz premium internal dac was not noticeable, i guess dac made noticeable progress between 2009 and 2020 but not much progress between 2017 and 2020)
