I'm fairly open to methodology. The 100W is headroom for a 50W or so amp (always go double right?) So I would say a 24 or a 48 volt main voltage, and at least a 12 +/- set of rails for preamp. MAYBE a 5 volt line for digital (still hammering out the final design)
50x2=100. That's my story and I'm sticking to it lol jk
All kidding aside I was referring to overall power as opposed to power in dB.

^if you mean average to peak, that is valid...
pmpo and you can multiply average to x10 or more, so that 50 watts ave. is 500watts or more pmpo..

Honestly? I would rather build one. But just looking at prices of parts it may just be more practical to buy one. For some reason or another, be it supply and demand or just outright inflation, power components and PMICs are kind of expensive. That and it seems like there's an added layer of complexity when it comes to power electronics I haven't even scratched the surface of.
Now if I WAS going to build one, I would probably bite the bullet and spend the money on a board mounted AC/DC converter for the whole thing (something like this https://www.digikey.com/en/products...DJ22Ebslvs3XEHFJAFVFeTEAeWQAWWxUTABXWWx1NTUgA wow that's a long link) and do the DC to DC conversion myself since that's a bit more managable since I don't have to deal with waveform manipulation. That and AC/DC is usually larger components so if i can cut down the size on that then all the better. I'm just not sure what overall efficiency would look like...
