I've always sort of liked the classic "GE" tape head/mic preamp
circuit:

but it occurred to me that it might also make a nice headphone amp...

Audio tends to be nonsense, but at least the audio guys have fun
playing with circuits, whether they make a lot of sense or not.

Even though you scorn and ridicule audio, there's nothing wrong with
anyone seeking perfection there, just as there's nothing wrong with
your search for perfection in the genre which pleases _you_ to pursue.
So, speaking of fun, why don't you do a complete design and assign
values to the circuit components and identify the semiconductors?
You're not playing the game. You are sitting in the henhouse, clucking
about the people who do.
He's not playing your game, which involves telling John Larkin how
cute his circuits are.
He's not designing circuits, which is what this newsgroup is about.
You aren't either. Both of you start to cluck and peck when people do
design circuits. No surprise.
Or is that legwork _we're_ supposed to do in order to flesh out your
divine revelation?
Chickenleg work!
It's half the story - a few component values make it a lot easier to
work out what a circuit is doing.
You can't look at a circuit this simple and see what it's doing? OK,
no surprise.
Without the component values, it does take a moment's thought, which
is wasted on a bizarre (if simple) circuit with few potential
applications.
Millions of the "GE" circuit have been used for decades. The mosfet
hybrid is a very reasonable headphone amp.
Post a circuit, doofus. You've forgotten how to do anything but whine.
You are the one who complains all the time. You may have personal
preferences about the nature of the threads that get started here, and
the responses that get posted, but they are only of interest to you.
You are welcome to demonstrate your preferences by choosing to get
involved with particular threads and in your particular reactions to
other responses, but your whining about the nature of those responses
doesn't make the group a more attractive or rewarding environment.
In the meantime, I'll post a circuit when I've got a circuit worth
posting. Posting a example - without comnponent values - of a circuit
that has been used in millions, for decades, doesn't strike me as a
profitable use of bandwidth, but that is a personal preference.
