Flutter is the 7 letter F-word in aviation circles. It was first documented in 1916 by Leonard Bairstow. Flutter can be serious, see this Youtube video of aircraft:

The infamous Tacoma Narrows Bridge was a victim of flutter:

Amusing Diyaudio thread on the Tiger amp which had a reputation for thermal runaway.

Bonsai (after William Blake)

Tiger tiger burning bright,
your output circuit is black as night
Your front end looks great
but its the overall oscillations that we hate
They are, we fear, linked to that Output stage
and that really shows your age
For the culprit is that common collector
that really screws the transfer vector
We see excess gain and poles galore
and then, just when we thought it safe, even more
no miller capacitor just like Doug told us
this I tell you is why there is a fuss!
So friends, lets ditch this burning design
and go for something a bit more benign.

Actually looking at the circuit, Bonsai means commoned collector, as the  output stage is common emitter, which may explain the tendency for thermal runaway.

Not hifi but worth saying:

Father Pierre, why did you stay on in this colonial Campari-land, where the clink of glasses mingles with the murmur of a million mosquitoes, where waterfalls of whiskey wash away the worries of a world-weary whicker, where gin and tonics jingle in a gyroscopic jubilee of
something beginning with J?”

What an immersive, cutting-edge articulation on the state-of-the-art in audio literary achievement. Punching well above your weight class, your words removed an invisible veil and allowed everything to just snap into focus. Like turning on a light switch, it made a night and day difference providing the dynamic ambience necessary to result in an order-of-magnitude epiphany. Courtesy XEagleDriver

The article that prompted the above 2 paragraphs:

Good example of the genre follows:

“But the Qutest offers more resolution here. Greater texture and nuance cling to the wheeling cymbal, double bass plucks and Porter’s honey-thick vocals, all of which have plenty of room on the Qutest’s expansive canvas. Its presentation is slightly bigger and more spacious than that of the DAC it replaces, giving musical elements greater scope to evolve without bumping into each other. We play Peter Broderick’s Eyes Closed and Traveling, and there’s a new dynamic facility to our system. The piano piece is an exhibition of Broderick’s ability to shift from delicate to devastating within a few strikes of the keys, and the Qutest faithfully conveys the undulating dynamics, clocking the sudden surges as well as the subtler simmerings. Notes have crisper, more distinct leading edges, carry warmth and texture in abundance, and never decay prematurely – even when forthcoming notes tumble over the top. Timing is that bit tighter too, which helps the Qutest sniff out a rhythmic structure when one comes its way. With Biffy Clyro’s My Recovery Injection it not only captures the dissonance of that stinging lead guitar but also how it coalesces with the walking bassline and slicing cymbals. That rhythmic mastery is further revealed as we play Spoon’s Pink Up. The impressive drive, for which we’ve always rated the 2Qute, propels the disco-flavoured psychedelica on its unerring journey, and response to shifts in pace is slick and natural. From the soundstage-filling shakers to the xylophone melody and glitchy vocal, everything orbits the track’s solid metric beat. The Qutest is as happy rocking out to tumultuous tunes as it is rolling with classical compositions.”
