Although I've heard what's inside Shigaraki DAC 2 years ago, a picture is worth a thousand words

The supply voltage to DAC was said to be 8V.

Eehm, u don't think there are caps on the other side? Correct me if I'm wrong, I'm not really familiar with Englisch/American forum-slang

As I said: There are - must be - caps on the other side. Do I write slang?

There must be a second regulator then, somewhere hidden inside the DAC (on the dark side of the pcb), or does the CS8414 tolerate 8V (maybe a smaller one or a TL431)?

Those are the caps I meant, thanks. The previous poster did me believe that he thought there weren't any caps there. But I must have misunderstood.

The other regulator is on the other side, must be

If I see correctly, they use a cable between SDATA and DATA. I thought this was one of the most important connections since the digital data is led through there. then why a cable and no hardwire between the pins? Am I wrong? They chose to wire FSYNC and SCK as short as possible. Can anyone think of a reason? Why are they so important? I can read in the datasheet what the pins do but don't quite understand it.

It seems to be a single side pcb, only the SDATA (pin26) - DATA (pin5) connection is on the "wrong" side of the receiver chip. Maybe the blue wire is then the shortest path. The other connections have only a short path on the pcb.

Bit clock and word select connections are surely as important. Without a correct information here the data stream is worthless, I think.
You understand by my words that my knowledge and experience about all that is restricted.
(I only think that the PeterDaniels pcb has a shorter path still..)

Thank you.

Has anyover ever experimented with hardwiring the SDATA against hardwiring FSYNCK and SCK?

And does it matter if I bend the pins on the chips? Sure, I shouldn't do it to much since the metal will break, but if it doesn't? Will I lose quality or is it just smart configuring?

Any ideas on the used voltage regulator? Could it be a 78xx? Or are those pins longer? Maybe they cut off a piece?

So many question and how many answers?
