AB class audio amplifier with high grade performance

If you look at the circuit (difficult since its quite packed, I am using differential input, and some bootstrapping). Im studing Telecom. Ingenieering. Cheers!

Telecomunications rlzz im studiyng it in high school :D

And btw nice job on the amp

W.o.w after few minutes of lookin and scraping my rusty skull i realize that i was lookin at ...the hell big full bridge uber complex amp. How long will u work to design such wonder?? And how u not get lost in those connectios when u implement it here.

But it has a crossover distortion and a lot of dc passes through the speaker. Is this normal? I have never come across such kind of amp

Actually is this extraordinaryn high input impedance do not catch bybacting as field antenna a nasty form of magnetic distortions and electric fields ???? Many ppl knows circuit so called Junction Fet E-field detector. Clearly demonstrate what happens when very high impedance and very low input capacitance is present. Is there some technique to bias input to counter act field detection and maintain still almost One gigaohm of input impedance. This is common problems ss i read various articles. One says that current loop based signaling is extremely fast and hardly catch any distortions because it act as a flush which clear other trash on his way by related to this curent electromagnetic fields also . Low input resistances of various current detectors also no need to worry about any type of noise or distortions cuz any of it ends sucked by nearest ground because input having almost zero resistance do not protect such induced distortions from flush out to ground. And logical is to use such system in high-end audio where distortions, noises and any other dirt on signal is highly unwanted . What is your opinion on this topic guys?? I personally cant pick side cuz i hear also a bad opinion about those current loop signall sourcing and as the only good method is voltage type signall feed to high impedance inputs this should give less distortions related to nonlinearities that arise on active elements when they are loaded by currents. This is heavy topic but i feel that crrent loop seems more reasonable way.

WOWWWW

Cool, nice work, but isn't that too much just for 400mA?

Ok, do we have artwork for the circuit board anywhere? Maybe parts list too? Just curious. Might want to post this kind of work on DIYaudio.com

Yes, will post link to pdf with parts description soon. Cheers

Hmmm but u did not answer to many questions bout u amp huh?? Lol he cheers everyone and simply vanish. As if he wasn't see those many curious things ppl want to ask.

This is your 16th comments. Lol.

Hello all! And thank you for your pacience, here I uploaded all sort of details. I hope you like! http://bit.ly/1dsh5vk

Simulation shows considerable distortion at phase transition point - could that be related to the pullup at bases of symmetrical pnp transistors where maybe a pulldown may be needed? It seems that pair can never open as it is now.

The 820 ohm resistor top center is the one I refer to.
