Long time former owner of Revel Salon1. I am changing from the Revel Salon1 to the Thiel 3.7. No technical explanation other than I liked the way it sounded way than the Revel. I have also heard the Studio2 and it did not move me like the Thiel 3.7. Never heard the Sophia line.
You need lots of power for both the Thiel and Revel.
I plan on building a HT system with Thiel 3.7 + 3 SCS4's + cheapo sub. I currently only have the SCS4s. These are supposed to have some trickle down parts from the 3.7 (tweeter???). After 3 months of ownership I am extremely pleased with the SCS4.
