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?


Many for me would be any that I come across. I flip through the hifi
press every so often, and I think I'm not far off correct in saying
there's hasn't been a single example in the mainstream media?! Which?
(UK consumer mag) do blind tests, but not with the rigour you require,
and they frequently report differences in amps (and CDPs come to that).


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


Yes, we've done this, and I set out a few problems I had with your
methodology and method. Even so, and FWIW, I found your tests
interesting and valuable, if not entirely persuasive.
