This one from this message ... http://www.diyaudio.com/forums/pass-labs/325037-faow.html#post5489346 ... it is also a follower with no gain. 😀
So what's your point ?
How is #164 different from #1 ?
The circuits posted by Michael all have gain.
That was what the previous discussion was about.

I do.
1W into 8R is +/-4V.
A typically modern source is 2Vrms, without volume control.
A phono pre probably quite a bit less.
So 10~20dB gain is handy.

For SE topology, a good quality L is less demanding to manufacture compared to a transformer with a caveat of a coupling cap. Is your preference to transfotmer coupled topology based on measurement, sonic taste or something else? Would you kindly share a bit more of your experience?
No I don't build amps with audio transformers.
I just find Michael's circuit interesting for its minimalism.
At least not as boring as MOSFET followers with coupling caps.

Are we to expect another late night trip to the bowling alley will be happening soon?😉
@ Mr. MR
I was contemplating variations of SE output stage. Quoting Audio Note's Kondo-san: "The most significant mistake of theoretical audio maniacs in this century is that they threw away the OPT." My sims on OPT coupled MoFo however, show inferior performance compared to the LC as you designed. As a bonus, chokes are less fiddly to manufacture.
Of course I also understand that there are other issues when an electrolytic cap is used for signal coupling duty. One notable example being guaranteed messy incident on incorrectly installed polarity. 😀
Seriously, I really am curious on issues related to LC output coupling I may not be aware of.

Since I can't make it to BAF this year, I ought to put a little pre-show appetizer together again.
Fingers crossed that 2019 will be my year. 🙂
