How to improve power supply?

My pre has a separate ps and it's very inadaquate.
It's from the mid 90's. What are the most important parts upgrades since then?

Doesn't it make sense to get rid of these stray magnetic fields for once and for all?

Toroidal transformers are no exception. In addition, if feasible, should be decoupled from the chassis by removing the bolt and by placing a layer of cork beneath the transformer, isolating the sensitive circuit boards from the transformers.
