If you doubt this, just carefully observe audio-salon demonstration

(or even your own demonstration protocols) The salesperson ALWAYS turns the
volume control ALL the way down between comparisons and then controls the
overall level on the comparison. There is NEVER an attempt to match levels
.... EVER.

At Optimal Enchantment in Santa Monica this has never been the case IME. Same
for Acoustic Image in North Hollywood. They have always given me full control
of the levels in any comparisons. They have always just hit the mute switch
when changing over components.

This won't necessarily match levels either because input sensitivities can
vary. My point is that levels are never matched except by Kentucky windage and
that floor personnel will, over time, employ techniques that tend to sell
product, even when they may not be consciously aware of the particular bias
mechanisms.
