So much depends on your abilities and construction skills... and on what you call simple.

Would you make your own PCB's for example ? or do you want something that has PCB's available to buy.

Sounds to me like you might be better off with something like a chip amp (LM3886 or similar) built on boards that are readily available.

Yeah chip amp will be good for you. In transistor amps simplicity (of the schematic of course not in building) is in negative proportion with efficiency.

If you don't mind a little tricky soldering, something like the ADAU1592 would be a good candidate.

If you want easy, plug&play I'd probably go with an LM3886.
