I have Thiel CS2.3's and used to drive them with Bryston 4B-ST and recently switched to Sim Audio Moon W-5. They sound fine with Bryston except if you want to listen listen at high spl's. They sound much better with the Moon W-5 with dynamics benfiting from the Moon's control and current plus the Moon has a touch of sweetness up top.
I recommend any amp that doubles down into 2 ohms (at least 700-800 wpc into 2 ohms) and has output impedence of 0.01-0.015 ohms.
