And I'm talking about perceiving differences in audio
reproduction equipment when reproducing music, as
evaluated using ABX.

ABX is known to work very well.

Where's the beef?


Some listeners, including myself, feel that a period of longer term
listening (at least several hours) is required to reveal itself. E.g.,
could it possibly be that certain distortion characteristics are not
apparent nor find oportunity to 'grate' during instantaneous type
comparisons?

I think this is flawed thinking. If there is a difference between the sound
of two components, ABX or any suitable DBT will illuminate the differences on
direct comparison, immediatly. Any differences that require long term
listening to uncover, either are too miniscule to make any substantive
difference in any listening experience or they are imaginary. That's been my
experience.
