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.

Not sure what you had before or what you changed to but if you love the amps so much (which you should their fantastic) why didn't you try speakers with higher 100+ sensitivity? I've heard a Classic Audio T1.5 and Volti Vittora fill large spaces with ease.
I tried out a few high efficiency speakers and they didn't come close to working well in the room given its size. The Classic Audio and Volti speakers you mentioned would indeed work, but are far, far beyond my budget, even used. 

The room is 25 wide, and is completely open into the dining, fireplace and kitchen area behind it. It also features ceilings that vault to 20 feet. 

No problem with pointing out the speakers I purchased after they were clearly able to work optimally in the room. Vandersteen 5a's.
