As I always do, and I never saw a DAC, or a preamp, or an amp, that sounded the "same" with different circuitry and different chips.
In fact, I am yet to hear a microphone of same brand, and same model that sounds the same.
We used to stereo match mics at factory level when I was in a recording studio work.
Amazing how we are having conversation about "educating" yourself, when you guys stress the fact that it sounds the "same"
Maybe, go explore that theory on blind test.
Talk is cheap. Show us a double blind result where you can reliably make the difference between 2 recent dacs.
We never saw a successful one.
People are not able to differentiate between good amps, so for DACs no way. The differences are order of magnitude lower than what the human ears can differentiate.
If you want to believe, that's fine but you may not be on the correct forum
