Daanve,
It is both. It is Single Ended Push Pull, where the upper device sets voltage on the load, and bottom device sets current demand to meet the voltage requirement. This is a very old technical name, I believe given to a very old 1950s design from Murray in Australia using tubes.
This is a difficult concept to grasp - but the harmonic profile of the amplifier, despite schematic appearances, is pure Single Ended. Not quite the same, but very, very close, and much more efficient.
There is no requirement to explain anything to X, Daanve, if you knew him as I do you would realise he is cleverer than you and I put together.

Hugh

Dannve - Let’s just call it “George”.

But seriously, no more pedantic arguing or snarky comments about what the topology is or isn’t. For almost 30years the Aleph-style amps are traditionally described as single-ended with an active CCS that tracks in sympathy with the load. The inventor and holder of the patent talks about this at length in various articles.

If you wish to discuss/argue about this, start a new thread. I’m sure there will be a lively and stimulating debate.

Mmmm ... possibly because you persisted in jumping in, boots and all, to push your PoV onto the respondents at every available opportunity?

Thank you so much!

Even if I don’t quite understand I’m happy to build my amp and listen. However, I was hoping for more subjective feedback, if any was available.

Hugh, when will you tell him it's not?
Daanve, please stop it! You have made your point and it did not stick. Does it really matter what class amp it is, if highest fidelity is the objective?
