Music in my life - system history

My last news from the system - 4-th version of DIY DAC.
After I changed my amp to Pathos Logos Mk2 I have feel - the signal from DAC isn't enough when the power is required.
As I have made the full power supply here, I have rebuild it to use more capacitors to be more powerful. Also I have removed unnecessary parts used in previous version of DAC as analog volume control used instead of internal volume control in amp from China.

Then I have heard the huge difference with my new Soekris 1021 implementation.
 
Now I'm building linear power supply for Raspberry Pi 4. I hae checked how power required and found in mode of picoreplayer upper value is 1.5A during power up and 1.1A when playing.
So I have now transformer up to 2A

This transformer is hand made.

Than I have prepared and ordered PCB board developed by myself. 3D model shows how it will be:

Waiting a little bit more to receive the PCB's and in parallel checking parts.
 
Heh, now I have PCB ready and tested.
All works fine and stable power is very good. Under 2A load I will check, but seems no issues.

Looks very close to 3D emulation.
