I was just surfing and find all the different opinions interesting but at the the end of the day it's what type of music you listen to and what you end up hearing from your speakers.
I currently own the B&W 802D's matched with Brystons 7BSST mono amp and Bryston BP26 pre-amp. Honestly, at first I thought they lacked the base punch and tried Rel 505R sub which was fine but when I changed my speaker cable to Virtual Dynamics Master. Wow!!! what a difference in sound that allowed me to sell the Rel sub, so cable do make a difference and it's only by trial and error until you find the sound that makes you comfortable. OMP and best of luck.
