It must drive objectivists crazy that we measure the performance of our stereo systems through internal equipment called emotions. A foot tap, a smile, a chill up the spine to register good sounds, a grimace, scrunched eyebrows, or squinting eyes to rate those objectionable qualities to music. And what's perhaps even more frustrating must be that these measurements are irrefutable. More than that, they don't require understanding or explanation. They just are or they are not. In fact, I would go so far as to suggest that nearly everything in science and measurement stems from these emotional gauges. We study what makes us feel good or bad. We hope to understand why some things taste the way they do. We research to explain how and why we react to sounds, tastes, smells, sights, and sounds. Once we understand the mechanisms we can then control and manipulate them. Sometimes. It isn't science that dictates feelings and emotions. In fact, it's quite the opposite.
