Audio Power Amlifier

Any body tried this circuit? i'd like your feedback on its performance
 

Re: Audio Power Amlifier

I think this circuit will give medium to very low performance, depending on pzer supply print design etc.

The differential input stage can be improved dramatically by use of current sources and current mirrors for example. It all depends on how difficult and how good you want to make things. Maybe you find some interesting info on my site, i'm working on an amp myself.
