Hi John,
Yeah I know its not perfect but I want to see where it leads. When I find more time I will calculate for some amps that I know the sound of better and will get a feel for if it is making any sense or not. I will throw one of your halo amps in the mix as well...just don't shoot the messenger if you don't like the result ;). What I real like in his thesis is this derivation of the Aural harmonics. They get brutal for most amps around the 4th to the 7th harmonic. The 2nd and 3rd end up being nearly completely trivial. For 87 dbA (my surrogate 1 watt assuming an 87db speaker) the 2nd Aural harmonic from Cheever's equation is nearly 6%! For the third though already it drops to .07%. At 97db (my 10 watts) the 2nd harmonic is up to nearly 17%! The third is still quite low, around 0.2%.
