I know many report hearing better low end from passive bi-amping and, as you have indicated, you now have an amp that is not losing any power to produce the top end of the spectrum it is able to push a little more for the low end requirements of the speaker. Is it a night and day thing? I haven't read anywhere that it is and in my own brief experience the benefit wasn't worth the effort but I didn't have an amp set up like you are proposing. Give it a try \:\)
