I also still have my natty copy of the 'sliderule' he had sent out with one

confess seeing this was one of the things that prompted my curiosity and
lead to the HFN article I mentioned. Like yourself, I suspect, I've spent
far more hours than any sane person should watching a scope display, etc,
of power amp output whilst playing music to see what demands the music
waveforms place on the amp and speakers.

Some time ago John Crabbe reported published work in which listeners'
perception of the same absolute loudness was rather different when they
were listening in a large concert hall compared to a domestic listening
room. This would suggest you do indeed need less in SPL terms at home
than you get in the auditorium.
