Default KA30se "KRYPTON" SE class A amplifier

This is the finall version of the amplifier I`ve been working on lately. It is a class A amplifier single ended with impemented "aleph ccs".

30W on 4Ohm load
Open loop distortion @ 1W/4Ohm = 0.03
Open loop bandwidth 48KHz (-3dB)
CL distortion @ 95% power = 0.08%
CL bandwidth 480KHz

What I`d like to ask is it comensated right and is there any specific type of compensation i should try?

BTW the sound is VERY good and precise nothing like the classic SE amplifiers..

Thanks in advance, Borko.

There are many knowledgeable people on the DIY audio forum; maybe
you should be more specific about 'comensated'.

Seems very nice Bogdan, but the schematics are not very clear (at least not on my computer).
