Looks a lot like a Pass A40 with a DC servo added.

The regulated supply is nice.

Pass A40 boards are still available from AudioXpress for $6, a heck of a deal.

The design of the power amp is very straightforward (without the DC servo). But the main difference with most power amps is the REGULATION of the supply for the output power stage also!
This is in line with extremely expensive audiophile latest amps like Classé Omega, Halcro, etc. But to be effective, the supply regulation of the power stage must be carefully design with a lot of current availability.
