hey all, an update, I had the opportunity to audition B&W Nautilus and B&W DIamond. I felt the Ns were sad when compared to my Matrix 805 ( i really dont understand though how a new age speaker from B&W can sound inferior to their old speakers!) and the diamond was definitely much better than my Matrix, the highs were smoother compared to my Matrix.

But the price of Diamond doesn't justify a purchase as an upgrade!
