Hello,

A complicated diagram that will be very difficult to put into practice. Imagine that you have to balance very well on the differential input stage voltage amplifier. With so many transistors in that stage, is very difficult but not impossible.

Your amplifier diagram will be a regrettable adventure DIY audio.

Let us know if succeeded or works this audio amplifier!!!

Best regards

This monster, as you called it, I already faced splited in two different amps. Exactly the same VAS stage I employed in my StereoLith amp which has different output stage and exactly the same output stage I employed in my ProJet Power Amp module. So I said to myself why not to combine these two excellent parts in my next Maximus Power amp project.

So be it.

I will gladly take a role of a knight to face a "monster" amp and beat it.

Well, that's certainly ambitious.

Yes it is, but you probably don't know that I'm listening my StereoLith amp for a quite some years now and it is still simply the best sounding amp I had in my home.

After building StereoLith I said I'll never go to built such demanding and time consuming machine again, but as always, never say never again ... so it came that this year brought me a new pair of big speakers and I tried very hard to move some heavy amps to my home (Burmester 911, Esoteric A-03, Plinius SA110 ...) and still my homemade amp was simply better, more musical.

As you see now my only choice is to go further on from my verified past stages and do something, maybe even better.

Well it may look frightening at first, it's a big schematic, but the concepts inside it are all familiar. Seeing as you have proven out the building blocks already, seems that it has a chance. How on earth you optimize it though, lots of variables and pcb layout is a project all of itself. Looks as complicated as some commercial designs I've seen published around here.

I bet Digikey is looking forward to this too
