There are an extremly wide range of monolithic integrated circuits for audio power in the meantime, that contains internal mostly a LTP, VAS with vbe multiplier and power buffer in darlington or Sziklai-darlington configuration, sometimes also a totem pole MOSFET stage.
What IC-type is to prefer (only from the audible view) for full range applications and for tweeter amp in multi amping systems?
And a second question:
Are there IC's with internal topologies according the mentioned kinds listed about
http://www.diyaudio.com/forums/soli...e-ended-related-solid-state-output-stage.html
(except http://www.amplimos.it/images/N-CH1.JPG - this is similar to the topology from TDA7293/TDA7294) ??
Thank you for your advices.
Very interesting are ICs with internal topoloies like this one:

Judging by the numbers of reports we see that claim improved performance from "their" implementation and supported by the number of reports we see of "not working properly", it seems it is down to the way the chipamps are assembled. PCB design, Grounding design, PSU design, all seem far more important than the actual IC.
I think you are barking up the wrong tree, the cat's already gone !

Ah also true. Chip amps do have distinct audio profiles, but like many other electronics, it's more about the schematic and the layout/implementation.
The most feature rich and easy to use I would say have to go to the Overtures. Though the TDAs are equally as easy under most conditions.
I've used premade boards off of primary eBay. Maybe you should look into that. Jim's Audio, I wanne buy, and some other chinese sellers do make good boards. I wouldn't buy their semiconductors or capacitors, but the boards are good.
