SF Power 1s with Thiel CS 2.3s Enuf Pwr?

I love the sound of the Sonic Frontier's Power 1 Tube Amp. I am thinking about pairing them with a pair of Thiel CS 2.3 Loudspeakers. Thiel recommends at least 100 Watts per channel to drive the speakers. The Power 1 has only 55 Watts but it is a Tube Amp. Has anyone tried this combination? Will it drive the speakers or do I have to go to a Power2 Amp with 110 Watts? thanks for your help. jts
