those values of distortion are only reached in a simulation with identical values of each transistor pair. Maybe a monte-carlo analysis should be done even when it takes a long time to simulate.
You also have to have a proper model of your DAC working into your input impedance, that is where most problems will arise.
I think 2 good opamps and a modern differential output DAC will give you much better results.

Hi,
why that complexity?? What is gained ... or better .... what did You expect to achieve that could not have been achieved with ~40 transistors less?

With an input resistance of 1Ω, the resistance of the source is irrelevant whether it is 1K or infinity.

A very stupid statement.
You do not understand what causes THD nor the way of reducing it.
Show design with 40 transistors by little, with similar parameters and then there will be a lot to talk.
I notice quite frequently that East-Europeans may have refreshing ideas, but some are not very polite in their communication, frequently calling other people being stupid.
Sort of unrecognized genius complex?

No. Because other person did not respect him. They can ask politely, but it seem they are jealous.
Why on earth should someone be jalous.
What a strange hypothesis for a non commercial DIY forum.

We used to fall behind and learn from people like Bob Pease and Bob Vidler.
But after them, everything became stupid.
We are following you and at a dead end, but we are still lagging behind.
There are still living people here who can think, but it won't take long.
We'll catch up with you.
Otherwise, we're just more honest and tell the truth.
When someone writes nonsense, we tell them so.

Good luck with accusing each other of being stupid instead of responding in a civilised way, a way of communication that fears for the worse.
