B&W Matrix speakers owners preferably

I have a pair of B&W Matrix 800s. Powered by a Krell FPB 600 amp and a ARC Ref 6 preamp. I have them quad wired. I am extremely happy with the sound, but now I’m getting a big itch to bi amp them or quad amp them. I’m ready to pull the plug on an ARC ref 750 and I would like to use these for my tweeter and midrange and my Krell for my bass on my 800s. Can I do this for these speakers. ?? And what do u think on the sound ? BTW I only listen to CDs and I have a Rega ISIS. I also use a Krell B&W BAF. Bass alignment filters. . (2) balanced.  Thanks.  Mike.
