i have tried various voltage regulators from switch mode to venerable lm7805 to new generation low drop outs (LDO). There is a jump in sound quality when going from switch mode to linear. but then you have to deal with heat esp with rpi 3b+. with your pi zero which i also love above all pi's i would try one of the newer LDO's if you are drawing less then 0.5 A. http://www.ldovr.com/category-s/118.htm
if you have more budget and enthusiasm and prefer discrete components over IC's these are super regulators: https://sjostromaudio.net/cart/en/super-regulators/17-419-ssr01-sjostrom-super-regulator-built.html#/21-output_voltage-5_v/27-voltage_reference-lm431 pi's and audio hats respond very well to the quality of the incoming power ------------------------------------------------------------------------ mcduman's Profile: http://forums.slimdevices.com/member.php?userid=66702 View this thread: http://forums.slimdevices.com/showthread.php?t=110091 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
