but what about the 5v supply.
fboe wrote:I have made some ekspirement with linear power supplies for the rpi3. First I have powered it with 5v at the gpio, which gave an enormous improvement. But then I removed the "crappy" onboard regulator (for 3,3 and 1.8v) at the rpi board, and powered it direcly at pp8 and pp9. Oh my.... another enourmous improvement in sound
