My opinions so far:
LM4766- worst PCB design, most parts good, amplifier IC, fake.
TDA8920BTH board, the Juan Jing one, pretty good design, sounded pretty good but most parts were chinese slave made.

IRS2092, good design, did not work with original parts, had to buy new ones. Driver and output transistors.

Mostly they are pretty good, but i rather design my own and get parts from digikey or TME.

If you want to design your own PCB, then you must understand what allows a PCB to work properly.
The same applies to modifying an existing PCB to improvement the performance of the circuit.

If you need to learn, then build anything and learn after that.
