Has anyone done any tests or have some user experience, what's your opinion on the best eurorack case, power and output module in terms of specs/sound?

I'm currently using an intellijel 7U TPS80W Max with nw2sio

The nw2s has been an improvement in sound for me as far as noise is concerned relative to the previous module that I was using which I shall not name.

Ofcourse every rack is different and performance is a matter of configuration, but let's say all things being equal and ergonomics/portability aside which power and output would you go with if looking for the highest fidelity?
