hi, luca,
i'm experiencing a very good matching, 8.5 v2 and magneplanars mg12 qr.
my advice is to listen to them, or, if your room permits, bigger magnepan models. clarity, speed, no blooming bass, beautiful voices are the first things that spring to mind. in my setup, no tubes anywhere (said by a tube addicted like i'm..), no regrets. just music.
