Bob:
I started posting a reply earlier when my computer froze. When I signed back on, I saw that Jack had very eloquently posted the majority of what I wanted to say.
What you have to understand is that your type of question has been asked ad nauseam and there IS no answer for it. Therefore, discussing it just gets old.
This is not math where absolutes rule. Some prefer Chevy, some prefer Ford. Neither is right. What one person calls fatiguing, another calls accurate.
The rooms make a difference, the material makes a difference, the preferences and experiences of the listener makes a difference. It doesn't MATTER how one other person describes it. It's how YOU like it. And that simply can't be discussed until YOU'VE heard the speakers in YOUR room with YOUR material and YOUR personal perceptions.
