I have the aforementioned Toshiba MOSFETs, purchased from DK -- here's the deal -- 4 pieces 2x N channel and 2x P channel = 4 pieces for $30 (i.e. $7.50 per unit). but shipping outside the US is going to be $15. PM if interested.
> under condition that greatest level of symmetry is what one is striving for
Isn't it a benchmark for Pass Labs, super symmetry ?

that's just side effect and side issue
my main goal is dominant 2nd, thus I can't care less for absolute symmetry of output parts

My goal is lowest possible distortion, uniform over the audio band.
Just like the Pass Lab X & XA series.
But each to his own.

as I see it**, .8 series is different in that, THD spectra tending to favor 2nd harmonic
though, as you said, everyone is having own preferences

well, that's 40W
see my contraptions, they're consistently having 2nd dominant in entire power spectrum
for example , XA252, in all 3 iterations
anyway, it doesn't matter - Papaways are mysterious ones ..........

Of course there are fun tricks that one can play with the Source resistors in the output stages of various Papa amps. Either to get better matching, or better un-matching. The F6 was fun to play with this way.
Most are going out tomorrow. USPS jacked up the price of Priority Mail about 9% in just a week.
