Sonic atributes ultralinear vs tetrode vs pentode

Trelja, choosing the midpoint on a scale may be simple math, but it's not simple dimensional analysis. Since wpc is a ratio scale with a meaningful zero, the proportions that Ralph referred to apply in this case. If this is confusing to you, you might ask someone who has had a beginning statistics course.

Audiofeil, thanks for the careful editing of my comment. You may want to take more credit for your creative work in the future.

"What first needs to be recognized is that 0 is not one of the endpoints for a comparison between triode (20 wpc for the example at hand) and pentode (60 wpc). UL (40 wpc) is exactly midway (IOW, 50% not 66.67%) between the two. As such, the word "most" can never be used in such a context."

Speaking of "fatally flawed" analysis, would you try to argue that 10000 wpc does not retain "most" of the power of 10001 vs. 9999? After all, 10000 is exactly halfway between 9999 and 10001. I've only been following this dialogue between you and Ralph for a while, but it seems to me that your zeal to show him up outweighs your interest in contributing to this forum. I could just dismiss you as a troll, but you actually seem to know quite a bit when you are not trying to bait him. I'm enough of a noob to be ignorant of whatever has pulled your chain, but I don't think that you are making much of a contribution by making it unpleasant for Ralph to respond to this forum.
