I am a fellow Thiel 2.3 owner. I am using a Pass Labs x-150 on them right now. I am saving up for the x-350. Like you said the more power the better.
Thiel 2.3's Power Hungry??
Every time I add more POWER to these they sound a little better. They open up and sound smoother. Has anyone had the same experience? How much power has any one thrown at the speakers untill you were satisfied?
