Specs and measurements can be interesting but ultimately unimportant. I listen to how a component sounds. How does it shine light on a performance. Consider visual perception. You have day light, incandescent, flourescent. Dappled light, shading etc. I listen to music because it's beautiful. It can come from a highly b resolving, or mid fi system. As long as it's interesting and shines light on the performance. Measurements are ultimately meaningless except as an exercise in engineering. But I'm not an engineer. I listen for the love of artistic creation and expression.
