Have we all stopped arguing? May I ask a question?
What's the best way to check if a power amp is likely to be stable
into a capacitive load such as an ESL?
I could put a 2uF cap on the output and look at the output on a scope
while feeding it with a square wave.
But is it likely to damage anything if the amp fails the test?

One old Rotel amp has a warning in the manual against capacitive loads,
which is a pity as it is a nice, low-power amp and not likely to make
sparks if the kids turn it up to 11.
