So I guess this is 'real' Nexperia
This is also real?

That looks like NXP, the antecedent of Nexperia.

I offer a complete set of project files in the KCad format - http://puredsd.ru/dsc2expra_rel.zip.
The project documentation and source code is published on an “as is”.
ondrejk53 found a small logical error in the circuit. Instead of U36 you need to solder 2-4 pins.

Thank you for all that you've contributed on this topic Pavel - you've taken DSD replay a significant way forward. I'm still amazed at how good my 2.5.2 version sounds!

Have fun with whatever you take on as your next challenge.

Ray

make sense...
still haven't digged enough in your schematics to get an idea of them.

for what is worth, i have already received all the parts and just waiting to get the new pcbs for the BB-Sender and the DSC-St!ck.

I will keep you posted... but if i have to guess, is far from ready to publish something good

i think the bom has some issues on U36.
in schematic is drawn like an inverter, the VALUE on bom is for an inverter, but the name is for a buffer.
so in the end is enough to use SN74LVC1G125DBVR instead of the 74LVC1GU04DRL
