My new M3ti Fronts and VP100 Center should be arriving in a day or so and I'm wondering what my best options are for surrounds using my current speakers. I can use either:

Cambridge SoundWorks Surround II 5.1 (multipole)
..or..
Infinity REFERENCE 2000.1

I use a 5.1 set up, and the speakers *cannot* be placed at the sides of my listening position, they are about 1-2ft behind the listening position. Since I don't listen to music in surround mode I've been using the CS surrounds, but was wondering if the Infinity's might be a better choice.

Any advice is greatly appreciated since I'm still pretty new at all this. Thanks!
