Ilquam,
not trying to be irritating, but why dont you try describing F6 vs F5. I know its personal and relative, but still interesting.

My comparison will be between the Teaser-6 and a balanced F5. So far, the balanced F5 sounds better to my ears.
I have a couple of mods to make the the Teaser-6 and I will then do some more serious listening.

This is what really matters.
I am looking forward to your impressions.
FWIW,
I grew up listening to all types of guitars and guitar amps. I got really use to the wonderful tone that you get from a personal listening session of a Gretsch and a Silveton with dual 12" alnico drivers. Dad just fired it up a couple of weeks after i went through it and replaced the tubes and some old caps and resitors. He fired it up and played a couple chords and I was just blown away with the sound. Yet to reproduce that sound with a loudspeaker, but then again, it only has to reproduce the sound of one instrument. ZM was joking about tone switch, but that pretty much describes where i came from. Perhaps you could say "colored sound", dunno. Read M2 review at 6 moons and I think you get an idea of what i think is going between F6 and F5. F5t kicks F5 but, IMO. Dunno why😀

I wasn't completely joking about tone switch ......... even if most of my switches are mostly in one position

truth be told, too many avriables to classify sound of amp, but it is fun none the less. Hope Papa is getting good laugh along with you. End of the day, that is what i enjoy most, a good laugh.
What is your guess about Pa's secret? Is it discovering "sweet spot" (aka load line), or additional circuitry?
difference is ,while I'm not, Pa is exactly knowing why he's laughing ......
sweet spot , most certainly
even if , without doubt , he knows how to make that with additional circuitry

Gm of output power devices matched to <1% or even lesser, and similar tight tolerances for the passives.
On his site he says beginning of the year. Perhaps it will get pushed up. He doesnt seem like the type to rush.
Not lowest distortion; but device matching; compare SuSy which must have highly matched devices to attain high symmetry. Loop feedback in Mr. Pass's F6 is to lower output Z primarily and secondarily % THD. His F6 is almost perfect before he applies loop feedback. One of his early posts [#14] said:
The transformer secondaries are set up to drive the Fets in a matched fashion, if that is what you're asking.
I understood the wording matched in his statement above to mean got to go the distance and match everything else; otherwise settle for a mishmash of mismatches; and this is not his practice? Besides, the writeup of the old classic in post #38 stressed using matched bjt output devices.
