Measurements are another tool that smart people know how to apply for example to help decide what products to choose to listen to so they can then make their subjective decisions about what sounds good more effectively.
What comes first the chicken or the egg?
How do you decide what products to listen to? A crystal ball? What looks good? What some guy on the internet or a reviewer says you should? Only the ones at the local dealer if there even is one near you? Only the ones in a friend’s house, if available?
Maybe. But if you are building a system with components, putting those into a room, and you want those components to perform well together and thereby have a better chance of sounding good or maybe even outstanding once you get that far best to learn to read and interpret measurements. Not that you might not stumble onto something good otherwise, but....facts matter. Especially technical ones. You can choose to ignore them but does not change the facts.
