Whatever. So your theory is that a DAC should change the sound stream? That is what speakers and headphones are for, introduce character there as it is almost unavoidable there anyway. DACs and amps, nope, they should be transparent.
I didn't say that I don't have a theory. I only mentioned that a lot of those dacs sound the same. If that's the sound you think is correct and you enjoy it then happy for you. Doesn't matter what you or I think. I see you post a lot in threads with these same posts.
