Is this circuit 100% clone from Lab Gruppen?
Lab Gruppen have a CCS circuit too complex. They require a auxiliary source. I have a plan make a high power amp, use symmetrical topo like Lab Gruppen, but keep more simple.

// You need mounting bias transistor to output transistors or heatsink.

How about the sound?
I hear some people says Lab Gruppen have better than other professional amp brands.

And price of them are expensive. Swiss made.
