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!!


Indeed - you've/I've caught me out on more than one occasion :-)

There's no easy way to explain the whole thing - I just find listening
to music a very different experience to listening to electrical equipment.
