DAC Differences

My point was simply that there can be biases AGAINST some things
sounding different as well as biases in favor of the proposition. While
DBT and ABX will remove the bias in tests where the participants DO
believe, for instance that cables all sound different , but it won't
remove the bias from people who DON'T believe it - unless, of course, as
you pointed out, they don't know at all what they are listening to. Then
the test would be free of that type of bias.
The above ignores a well known aspect of human nature which is to strive for
a positive result from any activity that requires substantial effort.
An ABX test requires substantial effort on the part of listeners so the
listeners will follow their human nature and strive for a positive result
simply because they are expending the effort and don't want the outcome to
be futile.
