IAN CANADA CONDITIONERPI Ultra Capacitor Conditioner Board for Raspberry Pi in Digital Sources, DACs, and Computer Audio Posted October 31, 2020 1 hour ago, musicbee said: I think you will find the PI2aes needs 24vdc to operate. The PI2aes also powers the RPI, via a 5vdc voltage converter on the board. Although this can be switched to external RPI board power. I don't think this would be compatible with the PI2aes. You would need a HAT such as the Ian Canada fifo q3/transporter or Allo signature etc. I just purchased one of these: https://ifi-audio.com/products/ipowerx/ Very worthwhile, powers my RPI4. Bugger, I also have a Hifiberry Digi + Pro HAT. Run it with a cheap LPS, sounds great.
