Well, obviously, in the days I was talking about, digital recording was
still in the domain of the pro, and tended to sound very furry by
comparison to good analogue.

When was that then?

However I remember having a bit of a heated argument about the realism or
otherwise with some test luminary at a Heathrow Hotel show back then.
Pointing out that the dc coupled amp was a complete waste of time as
speakers could not really do constant air pressure unless you lived
inside an infinite baffle enclosure in any case.

The point of dc coupled amps was never to get dc from the speakers! Anyway
living inside an infinite baffle enclosure would still not make a point to
it as there is an air path through the mouth to the back of the eardrum, so
our ears are not "dc coupled"

The point of dc coupling amplifiers was to reduce LF phase-shifts, thus
increasing LF stability within feedback loops, and to eliminate bulky and
expensive output capacitors.
