Only one. The first stage is AC-DC conversion, with no regulation. The second stage would be the regulation. Whether the first stage is itself subdivided into more stages is a different question.
A small update.
Talked to Infineon and they can provide Gerber files for the SMPS and Halfbridge. Only downside is they want serial number. So, two units need to be purchased in order to go through with that.
Designing a 4-layer board for me is a daunting task. It can be done, but gerbers would make life so much simpler.

I feel like we are going around in circles.
Why not combine the AC/DC conversion and regulation (as is mostly done in SMPSs)?

Fine, then design it. I am just saying that all of this is possible, and the current schemes you find on evaluation boards is multi stage.
I am interested in GaN devices at the moment for the size. Reducing the SMOS from, day, 169x100x50 mm to 60x50x30 AND make it cooler would reduce the size of an amp. Using GaN for the power amp itself would make great sounding miniature amplifiers.
At least me and mocenigo understand the future
Julf: My desire is the same, but you have to remember that the Infineon units are not designed to be sold as is, even if you can buy them. They are designed and sold as evaluation boards and for a 3rd party they need boards to be separate to evaluate them.
I can live with either. Redesigning and moving the halfbridge over to the main board should not be too difficult.

"There can only be one"
Good
There's also one mocenigo.
All others are fakes. Like a chinese cap.
Sound quality is the important factor. Musical quality is set in stone on the recording. Either a "musical" sound was recorded and the sound quality allows this to play... or it doesn't. If amp make something sound "musical" all on its own, then it's colouration. Whatever "musical" means anyway.
By all reports and by Putzeys own experience/design, the Ncores and the 1ET400A are not effected by differences between a linear PSU or Hypex's SMPS (unless of course the linear PSU is inadequate and causing distortion).

So what would be part of the inadequate and causing distortion ?
Say we are using the diya universal power and Toroidy audio grade, any problems with such a setup ?
