Bi Amping my B&W Matrix 800s

I have been thinking about bi amping my B&W 800 Matrix . I am now using a Krell FPB 600 with a Mark Levinson 38s preamp and a Krell B&W 800 Series bass Alignment Filter. With the B&W Matrix 800 speakers being quad wired. I have been considering buying a Krell FPB 300 to bi amp with my Krell FPB 600 using the Krell FPB 600 for the 4 woofers (2 on ea. speaker) on my 2 B&W 800 Matrix and the Krell FPB for the tweeters and midrange on ea. B&W 800 Matrix . Can this be done with my Mark Levinson 38s preamp? Would bi amping really do justice for my B&W Matrix 800s? And how difficult would it be ? Thank you all .Mike
