When I assembled my 5.1 system I used WP/7's in the front and Sophia in the rear channels. I could hear a slight difference, not a huge change as some would like to make it out to be. I sold the WP/7's and now Maxx 3's are in the fronts. The Maxx 3's are perfect in my room. I still own the Sophia's!
Nice do you listen to multichannel classical?
