Leaving aside hook up, burn-in, etc.,
is there some way you can log listener reactions to match what
receptacles/plugs they are responding to?
are listeners allowed to share their comments as a group in deciding what
sounds 'better' or 'worse'? (There is often 'groupthink' where people's
attitudes are influenced by the views of peers);
duration of playing on each outlet - the fast "a/b" type switch doesn't tell
much sometimes or can be misleading, partly because of the source
material that may be playing at any
given time, so some thought should be given, not only to duration of
listening on each receptacle/plug, but on the kinds of source material that
will be used- I would think a range of stuff that shows mid range, simple
acoustic instrument recordings, human voice that is not over-gimmicked in
the recording process; piano- critical, at least to me in assessing what is
going on in a system, etc. I will look at your system re source equipment,
but would assume the more revealing the source and program material, the
more obvious the differences, all other things being equal. Just out of
curiosity, are you doing vinyl or tape?
