B&W speakers and SF lower end


I had thought I was buying SF Concerto or Concertinos then I noticed the B&W 805s and the older 602s. I am buying soon. Any input?

Click on this link to search the archives. Just type in the keyword "B&W 805S" or "Sonus faber" or "Concertino" etc.
I plan to get an Outlaw RR2150 to use with them. I still not sure of that being a good match.
