my linear power supply didn't work, I think because raspberry pi 5 requires USB PD negotiation..
so I'm just using my old phone charger.. hopefully the UCPI 5v supercap board is good enough.. also the shieldpi does emi shielding and 5v gpio filtering and creates a 3.3V low noise output for the fifopi ma reclocker
I like to imagine the UcPi 5v supercap power buffer removes the noise from the phone charger.. then the shieldpi 3 pro removes the noise coming from the raspberry pi 5.. it sits right on top of the rpi5, the reclocker is on top of the shieldpi and the r2r dac is on top of the reclocker. so I now have a completely optimized solution 😀
When I get time I'll try adding these lines to my rpi5 eeprom
PSU_MAX_CURRENT=5000
[config.txt]
[all]
usb_max_current_enable=1

just upgraded my fifopi ma 1.5 stock clocks to accusilicon. a nice bump in detail and texture in music
It really looks great. I would love to buy one.
How can we reach you if we are not yet allowed to PM you?

My toy has arrived - it is,......,......................... unbelievable good. What op-amps mods and other things, this is truly awesome: more detailed, more cold aka real, bass is very controlled and the soundstage is huge.
But be careful if you play low resolution music it will sound bad because it plays exactly what you fed it.
I play it via a modest sistem: volumio -raspberry - Nvarcher super capacitor power filter - Nvarcher grounded grid tub pre - 2 Rotels 850 mono - Chario Constellation Cygnus speakers.
Thank you very much and hat off for your work !
