I was demonstrating a pair of speakers for my Father the other day. I was flipping through my CD carrier and mumbled "let me find a good recording." He asked what makes a good recording? I didn't have an answer. I always thought a good recording was one that was mixed well. Meaning everything seems to be at the same volume level...vocals don't overpower music or the other way around. But why do some discs sound better then others? And how do we know what it right?
