What would you use to test perceptions?

People who have been trained to detect differences. Everybody I've
seen talk about audio testing states that that detecting subtle
differences is a difficult task. I conclude from that that untrained
participants are likely not to succeed.


I must say this. If the differences are that subtle that one has
to be specially trained to hear them, and work at trying to hear them,
then to me,
the differences would be so slight as not to warrant much attention,
time,
effort or cost in my trying to attain the optimal equipment.
