is an extremely tough design problem. Probably thinking you can just start with the QSC Powerlight circuit and just parallel up 28 IGBTs and go with it. I's like the see the resulting mushroom cloud - the video would surely go viral.
For that kind of power level you either need to use multiple smaller parallelable supplies (regulation suffers but it works) or reduce the switching frequency into the audible range. In any case it would be more expensive that the rest of the amplifier. For a brute force amplifer like this I might be inclined to use an industrial isolation/stepdown transformer. 30kVA continuous rating would not be required. 5-10kVA would be fine - they can routinely handle 5X in intermittant service. If you are going to the trouble of using a switch mode soultion, you'd want a more advanced amplifier topology (like class TD or H).
Could very well be something like this. No kidding no joke - these are real. I was using three CA18's and an RMX5050.

How are you going to get 10kW of INPUT POWER connected to such an amplifier? That's a lot of current... and a lot of dissipation to consider.
Would be something if they were really functional speakers,
Just imagine the amount of air it would displace, stand in front of it and literally let it blow you off your feet 🙂

So, 5kVA toroid can be suitable? I know many manufacturers, who design the PSU for 1/8 of the maximum continous output power...

In my opinion using 5 diodes in series to set tempco will create enormous idle current, which is really not necessary. Again in my opinion I would run this beast class B.
I would say these could be the real deal.

10k amp...
Que the speaker from back to the future.. Better not hook to to the amplifier,, there's a slight possibley of over load!!!
