Would you consider expressing an opinion such as "SACD sounds great"
as inviting a discussion on DBT?

Obviously, and fortunately no documentation to prove that is needed beyond
RAHE itself.

If so, I'm at a loss to understand
what exactly can be discussed without inviting DBT harangues.

Nothing.

I mean, it would be nice to discuss the merits and demerits of different
equipment / media without having to be constantly and repeatedly
subjected to the same old mantras (e.g. "since you did not have a
controlled test, you imagined the differences") harangues.)

Yes, it would be nice, wouldn't it.
