Yes, I agree. DBT is not a trivial thing though, and
surprisingly (to me) there doesn't seem to have been
many rigorous tests to underpin the 'little if any
difference' thesis.

What would constitute many?

I've done DBTs of several dozen hi fi power amps, and
found near-total support for the "little if any
difference" thesis.


Sure, of course - and it would be stunning if it weren't
for the fact that, in a domestic environment, most people
couldn't tell the difference between two pieces of kit
after a couple of goes back and forth - even if *they*
were making the switches fully sighted!!

Yet another irrelevant statement from a member of the "great unwashed". The
relevance problem here is that the evaluations I'm talking about have been
vastly more extensive than "a couple of goes back and forth".
