I am currently powering Watt/Puppy 7's with ONE pair of ML 2.1's and an L2 preamp.(I just switched from "highly" regarded SS monoblocks). The room is approxiamtely 18'x15'with a 10' high ceiling. I completely agree with Audiogoon's description of the sound reproduced, the dynamics and the deep bass. I have found Wilson's, at least W/P 7's to be a great match with Lamm equipment.
