I have tried B&W Matrix 802 and SF Extrema with 150watts Jeff Rowland amp. Both sound great with huge soundstage, open mid range and no harshness at all. But musical instruments are more "REAL", "LIVE", and "Textured" on Extrema than Matrix 802. I personally own Matrix 802 and also listed N802 and Extrema as last two choices to upgrade my Matrix 802. My final decision is Extrema. By the way, be sure to have good power-amp ready to drive Extrema or you'll not hear any good thing from them.
