Bi Amp B&W 803s with 9BSST and 4BST

I am planning to bi-amp my B&W 803 Nautilus speakers with my 4B-ST and 9B-SST ( I have 2 channels available ). Which amp should I use to power the bass / mid-treble? I currently use my 4B-ST to bi-wire my 803s. Should I even consider bi-amping? Thanks for the advice.

Other information: Using Bryston SP 1.7 as my pre-amp and Transparent Speaker cables.

Just curious as to if my music would sound better by bi-amping since I've always read that it is recommended. My question essentially is which amp connects to where given the fact that they are different amps with different power

Well, I have not "always read that it is recommended." But why not just try it both ways and decide for yourself if you are willing to invest the effort. I would not bother.

The 4B-ST should go to the bass and the 9B-SST to the mid and tweeter. This should help reduce IMD distortion from the hard driving bass from reaching your midrange.

I think bi-amping is a great improvement in a difficult to power speaker. I used a 4 channel 300 series Rowland that was excellent, and no output matching issues. In my last pair of speakers the improvement was not subtle.
