What To Replace A Pair Of Lamm Ml2 Monoblocks With? Need More Power

Due to a move to a new house, and a far, far larger listening area, I've had to change speakers to get something that will optimally perform in the large space, which also features very high ceilings. I currently own the wonderful Lamm ML2 18wpc SET amps, and they are simply the finest amps I have ever owned, and perhaps ever heard. Sadly, they cannot begin to drive the speakers I purchased to meet the rooms demands. 

I am currently debating what would make sense to replace them with, which would still make me happy after experiencing the sound of the Lamm's for the past few years. I need something with at least 100wpc and I don't think anything solid state would satisfy my ears. Any recommendations or thoughts on the matter would be greatly appreciated. Thanks.
