I'll make the test even easier for ya. You don't have to tell which player
is which, only whether or not there is a difference when switching from one
player to the next. Of course, the person who is doing the switching has to
be able to simulate the same switching transient even when going from player
A to player A, otherwise the lack of a transient would clue the listener
that no change had occurred. This can be done by very briefly switching to
silence and then coming back, either to the same player or to the other.  Be
certain that with whatever method you choose, there is no clue from the
switching action that gives the listener a clue.
