Measurements do not tell you what a system sounds like either and in what room?
No but they'll tell you if an amp is going to struggle or not at different frequencies to drive a certain speakers load.
And it doesn't matter what room you have, it can't fix that problem.
So you need to "understand and absorb" measurement's and bench tests as well. Just because you you don't understand them, do not write them off, make an effort to learn how to use them.
After all every piece of equipment you have was designed using them.
