Some people want their kit to make sounds that them happy, some want it to measure well. Some want a dollop of both, neither is more correct than the other.

And when it measures superbly but does not make you happy ?

You are misunderstanding what's been posted. Markw4 posted unsubstantiated audibility claims on this forum and I challenged him. I didn't challenge his own entertainment via his audio gear at his own place.

You need to get a better grip on what's going on before calling members clowns because if you don't, that would be clownish.

That would be the person's emotional issue, not audio. Number of factors can cause that and one of them is FUD spread by audio electronics sellers.

Is that a question? There's a missing '?'.

There's no such thing as a 'typical DAC' - point to one in particular.

I fully understand what has been posted. I simply place the same value on your tests as I would on his claims of audibility in that they are of limited use.

I've always thought DBT to be one of the dafter test methods when applied to audio. What use to me are conclusions drawn from a snapshot ?

I suppose that is the only perspective with which you are capable viewing the issue.

I know of people who have modded those boards to make them sound better. Lots of work. Almost everything has to be changed out for best results.

Also, the stereo separation is not very good since AVCC_L and AVCC_R are tied together down inside the mulitilayer board. Probably not practical to fix that.

If you have already have a dac you like and balanced outputs are needed, you could build or buy an opamp balancing circuit for it. Or, transformers can be used to do it.

I realized that opamps In first stage In link I posted are single and not double like true balanced require etc using four signal Iouts from es9038 per channel
It Is like this even at dual es9038pro pcbs

Samoloko,
Not sure what you are getting at.

It is possible to tie all ES9028PRO outputs together in groups of four, then run them through two single I/V opamps.

IIRC, ES9038PRO has too much output current for that method without using buffered opamps. If so, and a board uses only two unbuffered I/V opamps then it should be that not all the dac outputs are used.
