Nice speakers ! Congrats!
love me some Focals. I would look for something warmish and full for amplification. My 836w speakers paired really well with tubes. Although they sounded great with everything else as well. I haven’t heard the Sopras so can’t really recommend anything. One of if not the best sounds I ever heard was a pair of Focal Utopia “post BE” not sure the model but they were really big. They were pushed by some huge McIntosh Monos. Jaw dropping!
