Advantages with an outboard power supply

There can be a lot of reasons why an outboard power supply might help, and it’ll depend a lot on the particulars of a given circuit and the PS specifics, but a good PS can certainly be an audible upgrade in some circumstances.

I built a regulated linear outboard PS for my Hagerman Bugle 3 phono stage, and it was a nice audible improvement.  Not sure what to expect if I upgrade the PS of my Topping DAC.

I'm thinking about it also for my Node but I have been reading some articles and watching some YouTube videos and they say it will not help a digital signal. So, I'm on the fence.

I've used Farad power supplies on my Chord DAVE and M-Scaler with excellent results.
