Don't know about buffer but using PS caps will surely help.

Congratulations, it looks like quite a bit of work went into that.

I have a Bryston, the guts of it are a 2B, and the bass is very strong (into my PMC floorstanders). What you built should have at least as much bass as mine.

So the circuit topology should be fine. That leaves components ?

Big power supply capacitors provide energy storage for the amplifier to draw on for big bass peaks so if you've got tiny caps, which it looks like from the photo, you need more capacitance on the power supply rails.

Thanks for your post, but please make all future posts in English. This is an international site, so we've made the use of English mandatory in order to have the widest possible understanding.
