The distortion would be barely audible
Wouldn't it...

looks like they gave honest specs.. for once on an amplifier.
wish they said how they tested THD and power etc though.. if it was using FCC or IEA standards.
those are actually very typical distortion levels for full output on a class D amp.
keep in mind though, distortion spikes when you get close to peak output from a class D amp, so it should decrease substantially at normal listening levels.
