You seem badly confused about level matching. You do it AFTER you put the components under test into the test system. The fact that one component is louder than another is simply the nature of things, and it is why we do level matching. You also seem confused about proper testing. It appears that what you are doing is a Single Blind test, and those have been known to be hihgly prone to being rediculously invalid since the early 1800s, and the fact that they proved the existence of horses that could decode complex spken commands and do aritmetic in their heads.
