Hey,
have a RPI3A+ with DIY AD1815 NOS Hat-DAC which has now a simple cheap PSU, which feeds the RPI. DAC is powered by RPI through GPIO.
Want to update the system with a linear PSU. Can give power input directly to DAC and feed the RPI as well through GPIO from DAC. So I need just one linear power input.
I am thinking about using a UltraBib1.3 by Salas vs new LinearPI+UcConditioner by Ian Canada.
1st would be cheaper, but more to assemble. I am a noob, but think will find help from friends and learn to solder.
2nd would be more expensive, but easier to assemble. just 2 supercaps to solder.
does anybody have recommendations or experience in sound improvement? what would be better? thanx in advance.

You may want to separate the DC feed by using two separate power supplies, one for the RPi and one for the DAC. If the one for the RPi can be a more ordinary Switch-Mode PSU or Linear Regulated PSU the one for the DAC needs to be of a high quality.
One should be able to hear an improvement using just two ordinary PSUs (on a reasonable quality audio kit connected downstream from the DAC).
Your budget and electronics skills will be the guide for choosing the right power supplies for your kit.
