I haven't heard the Sophia 2. Between the Thiel 3.7 and the Revel Studio2, it's the Studio2 hands down. Properly set up the Studios throw an incredible image, and the highs are much better than those of the 3.7. For some reason on these forums the Revel Ultimas are never highly recommended, but to my ears they sound more like the real thing than almost anything else I've heard. Your Anthem equipment should do just fine.
