This is a Japanese site that has a lot of tube and MOSFET class A amps. they look interesting on paper but unfortunately I cant read Japanese so not sure how good they are - the thing I liked is that a lot of the amps have osciloscope shots so you know for sure how good they are - something that I think is dearly missed in the audio business as not many of the manufacturers and fanatics are brave enough to show how their amps would perform.
Here is the link.

I am particularly interested in how the D-NFB thing works.

I got a kick out of the one built in the plastic Tupperware container!
They all have NFB, just not around the output stage.
With such low bias the distortion will take off above the class A region. The highest bias I saw was for 1.25W at 4 ohms, 2.5W at 8 ohms.
