After long years of trying and having issues with all kinds of power supplies, I finally got a Voodoolab PP2+. It hurts to spend 200 bucks on something that makes no sound, but since my tone has improved, my issues have disappeared. There was noise before that didn't really bug me, but I realised how much it was disturbing before, once it was gone with the PP2+
Reason I got it in the first place was that I had ground loops from non-isolated power supplies that powered pedals in front and in the loop of some amps, and those issues are gone. Also fits great under the pedal train2 with the supplied mounting thingies.
As said, 200 bucks is a pain, but there is a reason these boxes are on so many boards.
I heard that the BBE Supa Charger is isolated, too and supposed to be good quality.
