I will offer a slightly different viewpoint. When I got in this game everyone said not to passive bi-amp, because it would make no difference. I have found a different reality. My home theatre system uses Mirage OMD-28s, and I have them bi-amped, and tri-wired (audio quest gibraltar cables) with a Pioneer Elite receiver. I went from single amped to this setup, and when I did there were significant changes. I had my friend Bill listen to give me an objective opinion.
My speakers the sound plane became much more three dimensional, the bass was tighter and more visceral, and the mids and treble were cleaner. This isn't to say it will have this effect on all speakers, but it did for mine. I say give passive bi-amping a try and see if it makes a difference in your setup.
Even though my speakers can handle a lot more power than I'm feeding them, I can never even come close to using the power limits of the Pioneer. It is just too damn loud at -8 on the dial. The one additional change I made, that I think greatly benefited the setup, was to run two dedicated 20amp circuits. The Pioneer has one all to itself with a PS Audio Premier SC Power Cable. So there is never a limit on power being fed to it.
Hope this helps,
