Need advice on bi-amping


Hello,
I am thinking about bi-amping my front towers. First I will list the components I currently have or will soon have in my system that will be relevant to the question.

Onkyo PR-SC 5507 Pre/Pro( on the way)
Rotel RMB-1575 (5 channel - 250w per channel)
B&W 804D towers
(second amp not yet purchased)

At the moment I am using this system as my 5.1 home theater/2-channel music setup. The rotel amp only has 5 outputs so, they are all used in this 5.1 configuration. I have the B&W 804d connected to the rotel amp with a single cable. What I am thinking about doing is purchasing another amp so I can bi-amp my towers. The onkyo processor has the option to re-assign two of the surround outputs for bi-amp ability. I would then use the rotel amp to power my front towers and buy another amp to run my center and surrounds. This will be a passive bi-amp setup because I am leaving the stock crossover network installed. What I am trying to achieve is tighter, more powerful mid bass response and more detailed highs.

If I do passive bi-amp my towers, would I gain more power and amp headroom this way? It seems like it would work as the woofer section is seperated from the mid/high. This way each section is getting a full 250w feed and not splitting it. I could be totally wrong about this. If so, somebody please explain how this works.

In your opinion, do you think this would provide an increase in sound quality? I know there are some of you out there that are running your speakers in this configuration. What are the pro's and con's of doing this? Thanks in advance.

I wasn't sure if that would work the way I thought it would. I suppose I just need to step it up and purchase a nice stereo amp for my towers.
I might step back a re-think this. Probably just save my pennies up for a better amp.

Thanks for the advice
