Sakis, what is the topology of this amp, even just a rough idea?

no secrets about my amps .... it will be more important though to listen to the procedure and not the actual schematic.

What i a trying to say is that i started with a very generic circuit 3 years ago and realized that there is so much room for improvement ( even though its a low part count amplifier ) mostly using techniques like the ones mentioned above but also combine filtered knowledge from the facts given above and other similar thread or posts in the forum .

in a way i may also try to milk the mosquito trying to make such a simple amplifier sound as best is possible but i started with an amplifier i liked very much .

Resulting of all the above will be something like this :

---If you construct a DX amplifier with 1943-5200 or 1302-3281 or 21193 21194 or 3055 2955 i can guarantee you that each and every one of them will have a different sonic signature ( for example )

---Things will be by far more critical if you play tha same game with the VAS or the LTP

Now questions to be asked and answered will be

A) Not really sure if one must go ahead in such a trouble and find out which one of the sets ( and combinations ) will work for the best. One thing i am pretty sure about is that no simulator will tell you very much about it

B ) I wonder how many of the so called perfect amplifiers presented already in the forum had a similar study next to them before presented here or else were ....

happy regards
sakis

OK .... nevermind!
