I believe that DBT is unsuitable for Hi-Fi evaluation as the detection

The testing and analysis method does indeed have to deal with this
tendency to anticipate change.

Can anyone point to a Hi-Fi DBT test where no changes were actually made in
the source material to check that the audience could perceive no change ? I
think that the false positives raised by such a test would invalidate this
testing regime ?
