Post Subject: A "better" power supply does not necessarily need to be "bigger"Posted by rowuk on: 7/23/2022
Depending on the UseCase, many things can influence the sound. Rectifiers, snubbers, impedance, corner frequency, speed, an inductor in series, regulation, isolation from the mains grid all are parameters to consider.
I do not know of any really serious attempts to quantify what does what or why, rather I only see something designed and the marketing arguments AFTER its built. Considering that power supplies are not that complex, it should be no big deal to just try many and take notes.
I am not sure that a "better" supply improves dynamics. Maybe the audible symptom is dynamics, but even there, we have a lot to learn. In the case of a digital device, which part of the power supply needs to be "better"? Do the digital and analog rails need the same "fix"?
How do we know where the dynamics are limited? Is it more a form of overshoot or really an improvement? Is "more dynamics" better?
