Audio is a trivial application, they learn about power supply
design and amplification, which is pretty much all there is to
audio amplifiers, in their early years and then go on to much more
interesting and challenging concepts.

I see statements like this from time to time, yet I am not so sure
that audio design is "trivial." There are not many other design fields
where an amplifier: has to provide up to 30dB of voltage gain; act as a
voltage source into a wide and arbitrary range of load impedances
and do so in an unconditionally stable manner; have a passband noise

Non-trivial!


Thoughts, gentlemen? I would suggest that designing, say, a typical RF
amplifier is, by comparison, "trivial" but, of course, I may just be
missing something :-)


Indeed, so.
