However, regardless of how it is labeled, here is a further thought for consideration. Just as WAJ suggested the importance of the 200-400 Hz range, so does Jim Smith.
Many of you may know about Jim from his association years ago with Magnepan, as a dealer in Georgia, as importer for Avantgarde, and currently as an audio consultant and author of "Get Better Sound".
In that book he identifies one thing he believes one must have for musical satisfaction, "a flat to slightly elevated response curve in the critical region from approximately 192 Hz to 348 Hz." If that leaves you curious then I suggest you read his book.
For my own experience I will only add that I've heard many expensive systems that seem to emphasize detail but they fail to convey the emotion of the performance/recording. Then I could hear the same recording on a "lesser" system and find emotional connection. So for me it is something more than extensive engineering and ultimate cost.
