you can have the same dac on different boards and on one it can work perfectly and in the other it could hizz like crazy. there's a lot of engineering going on

you can have the same dac on different boards and on one it can work perfectly and in the other it could hizz like crazy. there's a lot of engineering going on to reduce noise and the analog part in the DAC is greatly affected by the rest of the electronics, it's not just ones and zeros. most people won't notice the difference of course but there's a reason professional audio equipment costs a fortune.
