Hi,
My opinion : this could be a bridged chip , with 4 quality inductors and some flat wires and it matters !
I would say it is a TPA3250 chip bridged or less obviously a MA12070 Merus bridged.
The amp gives 48W / 8R and 83W / 4R
The TPA3250 is a 70-W / 4R stereo module with 38V max supply... (the PA5 has a 38V / 4A power brick PSU)
We don't see the OP amps by the way... maybe under the D-01 enclosure ? differential op amps?? )))
You can see here that flat inductors perfom usually better than the other (at least with TPA3251 chip) :
Also interesting to read :
