The other thing to remember is what you are buying as you go up a speaker line is better bass performance. The Tweeter in all the B+W Nautilus Speakers is the same. Not everyone can afford a pair of N802 at $8000 List. A pair of N805 and a REL Stratus III Sub is $3300 List, less than a pair of $3500 N804s (maybe the same with stands). If bass performace matters to you, the N805/Stratus combo will kill a pair of N804, and probably give a $5000 pair of N803 a run for the money.
I attend over a dozen classical concerts a year and perform in another half dozen. I cannot reproduce the sound I experience in the Meyerhoff Symphony Hall and Kennedy Center without my REL Storm III sub. Not even close. My opinion is not based on any hypothetical theory about MHz, room resonances, or how the phases of the moon affect sound in Mongolia. It is based 25 years of real life listening. Even if I were to get a pair of mega dollar speakers someday, I will then start saving for a mega dollar sub to make is sound even better.
