Not sure what you mean by this. The DDDAC does not have it's own clock or oscillator on board. The DAC chips just ride on the timing of the incoming signal....to clock the DDDAC...
Thank you, so the SCK contains the same clock as MCLK.
Another question. Could this U.FL cable be too long between DDAC and Q7? 15cm / 6"
What is the symptom If too long?
If this is the case, can I stripe easily one end of the cable? The soldering is no problem for me, but striping....

I agree with many before me that the mainboard LF50 upgrade is def worth it.
These lt3042 regulators I mounted instead of the LF50 and LF33s on the mainboard. I did do it all at once but after two days of listening I can easily say it's better, more so in imaging.
Be aware, I use SPDIF (SHD studio source), hence the LF33 replacements. Which of the three contributes the most I can't tell

Yes. Sample rate is not so imporant overall. It all depends on the recording quality. There are many 44.1 kHz recordings that sound better than much of the high-resolution stuff.Do you guys (and girls ) like the DDDAC sound with 44.1KHz music?
I'm also thinking about better clocks for my DDDAC and not sure which way to go. Easy variant would be SC-Pure for sure. Maximum performance Andrea clocks!?? Which parts would I need for Andrea clocks? 2 SinePi for FifoPi!? 2 Clock board and PSU!? And some are talking about doublers. Very confusing for me at the moment. Can someone please share a simple part list? How much would be such Andrea SetUp? Sc-pure is about 450€ for two clocks covering all sample rates.

Finally I finished the DAC
Here are some pictures.
Stack on stack
The bottom part contains the PSU boards, toroids with shielding cover on them and the relay switch for the power of RPi + DDDAC.
The left PSU with heatsink is 12V capacitance multiplier type linear supply for DDDAC. The right one is the same but with 5V output for RPi4.
Also there is a 3.3V superregulator for FifoPi Q7 clean side and a 5V one for the ReceiverPi Pro II.
The FIFO Q7 PSU remains under power 7/24 to keep the XO warm. In the future the ReceiverPi Pro II will switch this relay too if SPDIF signal is detected.
On the upper plate there are the DDDAC and the Ian stack.
All the power wires pass through rubber rings to keep the wire insulation safe.
