Self-delusion is far more addictive than Single Ended Class-A-Holism!!!

Use MOSFET - based Gyrator, like I do. Let Gurus hiss and spit.

Here is my Preamp+ PCB, with Gyrator load of the triode, CCS load of cathode follower, and relay shunting of outputs.

He reminds me one more personage, I would not say his name. Everything that he can not understand is bad.

This seems like a start of a Personal Attack.

Don't go there.

Also: thread start count may not be a valid metric. Some otherwise brilliant people can't find the New Thread button. Some don't feel a need to start a thread for every good thought, but weave them into existing threads.

The mu follower is basically a common cathode amplifier
It is definitely not. It is a compound with new and fundamentally different properties and behavior.

Quote:
increased the dynamic load resistance perceived by the lower device, which as you are no doubt aware will greatly increase linearity and gain.
On the contrary, distortion will greatly increase, but it is not simply a matter of increased impedance, there is much more to it.

I'm not even a huge user of the mu follower, but it's a great single ended (yes, this is not a blanced, or push-pull type of stage!) circuit
Did Morgan Jones say so? But no, the signal is balanced (not referred) to ground.

Quote:
There is no "balanced action, and the harmonic content is very similar to a common cathode that is loaded with an equivalently selected load to the reflected resistance shown by the cathode follower and load resistor.
The harmonic content is very dissimilar to a common cathode, only odd harmonics being produced as one of many negative consequences of the balanced state.

Morgan Jones' book has obviously not helped you towards a better understanding of the present topic, which proves to be too elusive to treat for that genre of authors.

Many amplifiers proudly announced to be single ended are actually out-and-out balanced. Most people have bad taste, poor ability to judge sound quality and perceive the single ended sonic character as a nuisance. A "clean" sound is more widely preferred, that is to say, when a small portion of the input signal is transferred. It is efficiently accomplished by designing amplifiers as a voltage regulator / oscillator consisting of various balanced stages and techniques imported from the industrial sphere.

I do use the push-pull topology, but I don`t call it single ended or low distortion.
