Thread: PSU upgrade?

Hey!

I have noise problems in my rack. It's okay on studio monitors, but I hear that hum when using headphones. I have a cheap PSU now - Meanwell RT65B x2 - and decent bus boards.
Will a PSU upgrade change something? I was considering the Doepfer A-100PSU3 linear PSU. Any experiences?
