Need advice: Biamping vs. dual bridged monos

I am now the proud owner of two Classe CA-100 power amps. I had one, loved it, then saw another available at an excellent price and couldn't walk away without it. So now I've got two.

...But now I need some guidance. With two 2-channel amps, what is the best way to power my speakers (Magnepan 3.5 in stock form, no modifications)?

I could use the CA-100s in mono mode; in mono mode they are rated (per the manufacturer's specs) for 350 watts each into 8 ohms, or 600W into 4 ohms.

Or I could use them in stereo mode and bi-amp my Maggies.

Which method is generally regarded as the better method?

If I go with bi-amping, then I need to get a new preamp because my old Denon preamp has only one set of pre-outs. Or is there a suitable way around that too?

Any insight you all can provide is greatly appreciated. As you can tell, I didn't put a lot of planning and forethought into this, I just saw a great deal on a Classe CA-100 and couldn't walk away from it.

Thanks!

Thanks to everyone for your advice!

To answer Minorl's question: Yes, my speakers are set up for bi-amping. Each speaker has a pair of treble inputs and a pair of bass inputs. The speakers also come with a simple crossover box that is connected directly to these treble and bass inputs on the back of the speaker. Then, the user simply connects the speaker cable to the two inputs on the crossover box. But when bi-amping, I guess that I have to set this manufacturer's crossover aside and get a good active crossover. ...But I really don't know. I have no experience with crossovers, bi-amping, bi-wiring, etc. This is all new to me. That's why I need guidance. : )
