I second Dan. Go for the EP500 and just 2 QS8s. For movies, SACD, and DVD-A, it's all geared towards 5:1 anyway. The extra two surrounds use the same base signal as the other two surrounds - it's just number-crunched by your receiver/processor, sending a little more here or there. Please forgive my technospeak. With the multidirectional, room-filling QS8s, 5:1 will do just fine.
