Ok I am pretty ignorant about audio and need some clarification on a couple of issues about the 1070. I have searched this forum and several AVS forums and have read a bunch of posts about the 1070. But still have the following questions.

I will be using a pair of 14 year old Advent speakers as the rear surround for now. I want to make sure they can work ok with the 1070. The documentation I found on them says 6 to 8 Ohms. Will the 1070 be able to control them ok ?

Some of the cheaper receivers I have been comparing to the outlaw offer THX processing. How much will I miss the 1070 not providing this surround mode ?

There isn't an auto setup with the 1070 and I have been reading how to do it with a SPL meter. But it seems kind of daunting. Is it really that hard and where can I find some more info on how to do it.

Looking at buying the following Outlaw 1070, HSU VTF-3 MK3, Oppo DV-981HD and Aperion Audio speakers.

The room is approximately 3400 cubic feet and there are photos here of the layout.

Any and all advice is certainly appreciated.
