Default Cheap Wosong WA-205 Amplifier (Tripath TK2050, Class T)

Hi!
I've just ordered this amp (Wosong WA-205)
Your price comparison for Chinese shops - PandaCheck
As I love the sound of the Tripath chips (especially TP2020 and TK2050) I couldn't resist for this price for a fully finished and cased amplifier.
I couldn't find much about it on the Internet.
Has anyone experience with this particular one?

The first thing I nociced is that the amplifier is dead silent (powered by a cheap SNMP brick). Though, when powered by a toroidal with 80KuF Nichicon caps a lot of hum appeared. After changing the transformer with a regular E+I one, the hum was gone.
It sounds good. Anyone else?
