If you are testing all products at the same time, that would be true.

Look Cal, you made a global statement. If you want to admit that that you're
wrong, be my guest. If you want to redefine the problem until like one of a
million monkeys trying to type the works of Shakespere, you can waste
someone else's time.

However, repeatability, and consistency-i.e. the ability to compare
A-B and A-C without having B and C there-demand adherence to objective
repeatable standards.

If you're doing a listening test comparing alternatives, there is really
only one way to get the benefits of comparing B to C and that is to compare
B to C. So your claim is wrong on the grounds that your justification is
bogus.

Absolute level, not just relative, is needed, if
you want the results to be significant to anyone not there at the
time.

You don't need a voltmeter with NIS-tracable calibration certificate to
figure out whether your test level is more like 1 watt or 10 watts.
