Well made and very rubust. The heat sinks work properly having effiecient heat dissipation.
The chassis is rather heavy, but it is not a problem if you don't plan to move it often.
I recommend the pre-drilled base plate, because it is very useful when you want to fix the printed boards and the toroidal transformer.
The optional volume knob has also very decent quality.
It would be great to have a less sharp heatsink. Otherwise, it is fully up to my expectations.
