I’m asking here because some of the audiophile power supplies I’ve been “researching” on the net also appear in Raspberry Pi contexts. I’m hoping that someone who has a bit more DIY experience might shed some light on the perplexing hum I’ve experienced when I add charging to an iPad or iPhone while listening to my Audeze LCDi3 and then (gasp) touching them.
I’m trying to figure out if I should blow $50-$150 on a better USB charger…
