Direct-Coupled Hybrid Amp

[joehpj]

I was looking for sth DC coupled hybrid power amp for desktop speaker with no caps or transformers on either input or output.

While searching on google, I wanted to find jfet/tube differential, tube voltage gain, MOSFET/BJT current gain design.

Then I find this.

any opinion? Though there's a cap on the input.

Any other SE or balanced configuration will be welcome.
