Hiraga 20W class A

I would say yes, but you have to be extremely careful when setting the bias voltage.

Yes, my friend built one and sounded nice, better than the one with power transistors.
Do not be confused because of the separate boxed (enclosure) Power Supply.Jean Hiraga's Super Class-A Amplifier 30 Watt Class-A SONY V-FET output. 2SK82 & 2SJ28 - YouTube

Hello,
Looks nice .
The music sounds like typical audiophile elevator music. But that is just my opinion.

Hi
I only can say he sold it for a great price.
To listen to any video on Youtube depends on a lot of things.
From the recording microphone to the headphone. You know that. He uploaded a couple of videos I am not sure the quality of his recording.
All I can write what he wrote to me "it sounded better than the power transistors type"
He built both of them.
He sold the V Fet type because he built something 50W type which outperformed both.
You can listen to that video also.
