I have to disagree. I’ve been modding/tweaking for many years...
I have never heard any audible/musical improvements with any modifications to the power side of any electronics. I have done my mods to simplify the signal flow (removing fuses/switches), upgrading contacts (pure copper), more robust/solid connections (solder), and better wiring (OCC, Triple C). For me, as an engineer, purist, it’s a fun hobby.
If you really need to mod some parts of their equipment for better performance, shame on the OEM.
