Frank, my thought is that you have to determine the setup for all those speakers(which you now say that you'll do "over time")before you can intelligently analyze powering them. The 4306 may or may not be fully capable of the job.

Keep in mind that regardless of the maximum power capability of an amplifier, with speakers of average sensitivity such as the Axioms about 1 watt per speaker is used at a comfortably loud average level at the listening position in the mid 80s of decibels. Brief peaks use much more, of course, but at safe(to your hearing)levels receivers anywhere in the 100-150 watt area are capable of handling such brief peaks. Unused amplifier headroom is simply that: unused.
