Larryken is not bashing. His comments are accurate and quite correct. I agree 100%.
the most important component is 'you'. 'mindset' is more often than not what causes fatigue.
Vertigo, by the way, I think you should put the tweeter grilles back on. These tweeters are designed to be used with the grilles on, otherwise, I think the dispersion of high frequencies may not be what B&W intended. Just my opinion. I think they also mention it in the manual. Besides, this may even improve the sound even further.
