I'm glad you like it, Piersma.Thank you for the kind words.

"Connect cathode of D10 to the emitter of Q15." --- why does it sound like put a tiny bit of bleach in the coffee and you'll get a new dimension of flavor? Sorry, no offense here, I'm relatively new and halfhearted to audio, and that kind of circuit looks way over me. Kindly details please. Thanks again.

I like you amp, good luck simulating and building. (like OS always does!)

Maybe not the distortion boundaries , but the sound will be supurb .
Having the output stage out of the AC feedback loop has it's advantages.

One being that the "re- activeness" of the loudspeaker load will not be
reintegrated into the NFB signal. I've seen NIKKO amps and others that use this technique and they sound superb. The LTP/VAS will have PPM distortion with the DB output stage at around <.01% or less .... realistically.

Can't wait to see it .. Nattawa !
