I have the B&W 802D's. I asked this same question awhile ago. I settled on the new Purist Aqueous bi-wired speaker cables. IMO they sound wonderful...extremely quiet. The music seems to come out of nowhere. Crystal like highs and a wonderful bass. Build quality is something to behold too. Of course all this is relative to everything else, i.e. your amp, source, line quality...and most important, the listening room. These speakers need lots of clean power to realize their potential.
