"Whats it based on?"

Just kidding. It looks like an amazing piece of work. Hope it sounds just as great :)

I've made A/B board to switch between two different opamp on the fly.
I put Quad eight AM-10 vs APP992 => not hear the differences  :-\

RMAA test : Quad eight has higher THD -> 0.012%,  vs APP =>0.0091%  !
it would be nice if anyone has the original quad eight am-10 DOA spec  :)

thank you very much to have measured them,
I would like to add that APP992 has the same THD as at 1khz as at 10khz and something less at 20khz, often opamps have much high THD at 20khz for their reduced open loop BW.
