Why don't you call Pass (talk to Kevin) and ask him whether its enough power? That's what I did when getting a recommendation of an amp for my Thiel 2.4's. I was all prepared to spend a fortune on the XA series monoblocks and they actually talked me out of it, advising that for my speakers the X series was a better match, and that the X150.8 would be more than enough power. They were right. I've never heard a greater change for the better just by changing out a power amp. Its astonishing. Far more detail, quiet, and a little midrange warmth characterize the Pass products.
