Budd, your due deliberation before ordering is commendable and you'll certainly enjoy your system after the long wait.
Ditto to John B. on the biamping possibility with the 1015. You can't get more power to the mains by doing this; there's only one power supply section in the 1015 and sending it through two rather than one amp channel can't increase the capacity. One channel can't "borrow" from the other, so the power to each section of the speaker is the same, not doubled. As far as a use for the back surround channels, keep in mind that although there's no 7.1 format(6 discrete channels is the most)processing such as DPLIIx can steer surround material from 2 or 5 channel sources back to those speakers, where it belongs.
