Alternatively, perhaps, that a well-designed amplifier will have about

such a case becoming damaging?

Funny, that's very similar to the value I use. And it'll have a series
R-C to ground to stabilise the load the amp 'sees'. This technique has
been known for many decades.

Yes. I have always done the same. However some designers don't, and it is
possible for people to choose incorrect values, or use an inductor whose
self-resonance is too low in frequency.

Slainte,
