Nobody capable of reading competently could have possibly seen any "fallacy of authority" in the following statements/questions.
"Go actually read the articles instead of spouting off ignorantly. Stereophile doesn't do anything like a Powercube. OTOH, TAC didn't take an important measurement that Stereophile does: FR into a simulated speaker load.
Have you actually seen Powercube graphs for a Hypex based amp?"
You see, my statements
a) make no claims that anyone is an authority about anything
b) contain no reference to what any authority says about the topic at hand.
So they cannot constitute an appeal to authority. Please read more carefully, and choose words that rationally relate to the text you reply to.
Please point out a figure in a Stereophile article that is (to use your words) "the same type of measurements" as a Powercube. Since you cannot, because Stereophile does not take any measurements that show voltage output into different loads and different phase angles, my comment about "spouting off ignorantly" applies whatever your alleged education may be. You spouted off, showing clear ignorance of
a) what Stereophile measures re amplifiers,
b) what the PowerCube measures re amplifiers, or
c) both.

If that is the case, what did you fail to understand in your education that leads to such bizarre and unreality-based idiocies as the following from your post at 201.
"Wait, now all amplifiers sounds the same? Why don't you come out and say all speakers sound the same, to boot? "
Did that vaunted education not teach you the difference between a solely electrical process (taking an input wave and enlarging it) and the electro-acoustic process of converting an electrical wave to physical sound? An educated person could not make such a foolish comparison.
Oh, and for future reference, when one throws out buzzwords like "fallacy of authority" and "quantum level" for no apparent reason, that just makes intelligent readers think one is lame and tries way too hard.

And your point is what exactly? That controlled listening tests of amplifiers have shown that non broken amplifiers with flat FR into the driven load, low noise floors, and sufficient oomph to drive the loudspeakers the SPL used for the test cleanly, sound the same. There is no
serious (level matched, bias controlled) listening session that has yet come out differently.
That is knowledge obtained by
listening! The "model I use" is listening. But dumb listening (sighted, unmatched levels) doesn't tell us anything about audibility, except in case of gross errors. It can reveal a lot about the listener's psyche/gullibility, but not about the actual components in the signal chain. That's why we have bias controls and take elementary steps obvious to anyone with a functioning brain such as matching levels.
