For some perspective, Gary Dayton former marketing guy at Thiel and now at Bryston, replied to a post of mine on the Bryston Audio Circle where I asked whether the 7B-SST2 or 28B-SST2 would be best suited for the KEF Blade speaker. He replied back with his experience with the Thiel 3.7 with both the 28B-SST2 and 7B-SST2. Thiel marketing used that combination for many years for demos and shows. He said the combination sounded incredible and that is why Thiel themselves went with it.
He also stated that the 7B was more than good enough for the 3.7's but if you can afford the 28B it is a little better.
