Donated US bucks to buy and measure a low end Yamaha R-S202 receiver. It was available for $180 new in the US.
It's incredibly cheap and in my opinion competes directly with small amps such as Fosi V3 and Aiyima V07. Got 4.5k reviews on Amazon US according to Amir, so it's very popular.
It clearly has far more features than a Fosi V3, several inputs, two speaker outputs, headphone jack, AM/FM/DAB radio, bluetooth, remote.
The specs of the power amplifier make me suspicious, why would you want to measure at 10% THD unless marketing needs you to inflate the numbers?

The specs on the German site offer DIN measurements, this looks far more believable:

It only has been three weeks, so i expect it will be a few month before it's at the top of the queue.
