Anyone have a link to the Legend schematic?
I'm unable to navigate his site given the language barrier, might be nice to
have an index here to schematics, layout, etc. for each design.

I think he passed away

Classic circuit designs starting everywhere obsolete due huge benefits of Class D.

Lateral and switching Power Mosfets in Class AB amplifier
brought clarity in sound and many improvements compared to BJT output devices in amalog circuit design.

If you like tube sound, Dr. Bora Mosfet Design sounds very good compared to many BJTs amplifiers, with absolute clarity, but with the same Mosfets in Sigma Delta / UcD Class D design you will quickly kick almost all analog BJT & Mosfet amplifier regardless of whether HI-FI or PA into the Garbage bin or use it as a door stop.

Try it, you can believe me
