This is a nice looking piece. And the construction seems to be very good; it mostly feels like a quality piece. (One exception is the the volume control, which I use all the time; it's very wobbly, probably because it also pushes on a switch.)
But 30 watts per channel? Ridiculous. Best guess, this is a 1 watt amplifier. Maybe.
I replaced a 20 watt per channel amp with this Fosi. The old amp at 1 on the volume control is much much much louder than the Fosi at full volume.
This is a 1 watt amp, maybe less.
