I'll repeat myself here, but with a project like this one, I would seriously consider a three phase full wave rectified power supply. It's almost DC straight from the diodes.
I love to learn, calculator is smoking.... Thanks, I think if you put a lot of new tech into stuff you can do a lot more than conventional ways. I think after a month of this fun stuff the idea can be in place to do what is needed. appreciated.
I see that, wow.... Problem might 3 phase... I think a lot of people overthought all of this....It is DC straight from the rectifier - that's a rectifier's job.
It's kinda in my avitar... Ok, I won't mess with you, it has to do with a garden hose.
Allow me to recommend a fitting fan for that heatsink.
(mm, odd, howcome I feel like adressing you as Flipper all of a sudden ?)

I remember what beer did to me, coffee is the opposite. Flipper is just what the audio world needs, to be flipped on their heads! I remeber seeing that guy jumping out at 120,000 feet, imagine if he didn't have a chute...

something like this?
Genesys(TM) 3U 10/15kW Programmable DC Power Supplies from TDK-Lambda Americas
I think this is the variable rail model.. at least the idea seems sound... Just wish my welder had 3 phase output... They make 3 phase generators, and single phase to 3 phase converters.... It is a good idea that needs to be ironed out, it draws a lot, I guess it depends on the load though...

Sounds like pretty much any.. and probably to concert levels, 2000 watts per channel of class a at 4 ohms. Can't solve this project in 1 day but we are making progress. Power still isnt going to come cheap unless it's military surplus or a place that does have 3 phase...
You probably can ram the speaker wires together at full output and hurt nothing.

Forgot to say I love that pic, oh yeah, that $115 4500 watt heatsink is not the big one.
I'm sure you're fine.
But you are getting a quick picture of how much cost is involved with a
1000 watt Aleph.
It could be worse, the SIT-1 has about 6% efficiency or so. Imagine having
to source and dissipate 16 KW.
per channel.
It could be done though
