Agree with You Ralph about GE harmonic distortion study and their conclusion.
Same is for SET example You give,everybody know why in SET Amps GNFB is more Problematic than PP Amps:Basicly beacose there is no automatic distortion canceletation like PP amp doo,SET Amps generate allmost all harmonic distortion products,so GNFB for SET Amps is `must` and value of inserted GNFB is allways compromise beetwen real `Ear` Audio performance and acceptable measurment(Osciloscope) performance,and this is allways valid for SET higher Audio spectrum reproduction.
Any way beside that from above,the Bigger problem for most SET Amps is actually OPT(price/sound limitation/ degradation isue),think the acceptable and real good `Ear` sounding SET Amp is relative low output power(~10W)A/A2 class SE OTL Amp with moderate GNFB.
