Unless you've got a really big room you don't need the 948's. They offer exactly 1Hz more bass extension over the 936's and will totally overwhelm a smaller room.
I power my 936's in an average sized room with a 32 wpc Pass F5. It does an excellent job. They reward having the best amplification you can find.
