I do not understand this kind of reaction. Why would cascoding make a voltage source? And why are we 'Of course' talking about voltage sources? And do voltage sources really have no current limitations? (All 3 questions are rhetorically ).

Have a look at TSSA - The Simplest Symmetrical Amplifier (post #963) this is cascoded (at the 'vas'). Neither R8 or R33 are voltage sources. If a given design fits the given problem, than it is fine with me, but if I state my opinion then it is just that 'my opinion'. I still think that (Joachims remark) was about CS's vs VS's

I'm just trying to learn a thing or 2.

Christophe, i have checked your schematic.
Is R33, the bias resistor, really 8 Ohm ?

I think "cascoded darlington" was Esperado's continuation of the previous post about overkill approach (addressed to Joachim). "Of course" means you are correct with your statement, "but we were..." means that Esperado and Joachim were talking about that something else...

Yes, I presumed the same thing. But I'm surprised that you're agree 100% Then I'm curious why or how you tackle the issue...

O.k. I did backtrack down to page #80 and could not find any schema posted by Christophe (I just did it again ). I just see (in the previous message by Joachim) a reference to a schema, so if someone will re-post it, or show a link to it, then I will be a happy lurker again

I'm not an expert like you. Very far from that. Because I'm a beginner with very little achievement, I tend to value my works too high, even if it could be just peanuts in your eyes

Christophe's ssa-crescendo was posted in the other thread (The Simple Symetrical Amplifier). I prefer to use google than the search function of this site:

Give as a link to the schematic/s.
Add that link and your descriptive comment to post1.
