I'll say this - the average person would be wise not to leap into an active bi-amping (tri-amping, ...) project. It is not a straightforward or simple process. Developing amplifiers specifically for the folks who are up to the task of doing so is probably not something that a small outfit like Outlaw can reasonably set out to do. But the idea of active bi-amping has a great deal of merit, so long as you have the qualifications to do it properly.
If time and budget allow you to tri-amp your front three speakers, bestbang4thebuck, I'll look forward to hearing about it.
