I also sold my N804's to upgrade to N805's. Yes, this is not a typo. The sound of the N804's seemed to lack the dynamics that make pop and rock recordings enjoyable. I agree with Krellnot regarding the midrange, it did seem to be a bit agressive which made Diana Krall sound like she needed some Dristan. The N805's on the other hand have everything I could hope for. The sound is dynamic, transparent and highly detailed. The bass is excellent for such a compact speaker but that last ounce of weight is missing. I solved this problem by adding the associated subwoofer that Stereophile used when reviewing the N805's; the Paradigm Reference Servo 15. The amplification is a Bryston 4B-ST and BP25. The result is gorgeous. Other B&W Nautilus 805 owners take note, system synergy is extremely important otherwise you may be shortchanging these little gems.
