You correctly say and wish that there is no longer the same 502 PRO.
Speaking of 502 I wrote about a simple model 502 without PRO.
If 502 is fed to a linear PSU, and also to supply Rapsberry 3b with the same PSU, or even better, three with voltages of 1.8 / 3.3 / 5 Volts, and to pick up a digital SPDIF- BNC signal or a balanced SPDIF- AES/EBU, then you can get very high quality Sound. It's magical and it's amazing. I pay attention to the 502 board version number 6, so does not play, the magic disappeared, the sound became just pure and transparent.
So buy only version 4.

Michael do not change anything in this version 4 plate!
I replaced BNC Spdif and Sound became sharply worse, I was surprised.
about LME46900, it's true that 1 leg is connected to Vee-, it needs to be lifted and simply connected with the leg 3 through an audiophile resistor of 180-220 Ohm, and the temperature of LME46900 will decrease, it will be a little warm.
This information can help those who bought 502 PRO.
Can it make sense to post it on the site?
P.S. in Photo two best for Sound new Linear PS 5 Volts, 3 Amper.
Best regards,
