Steve,
Last week, I bought a pair of lamm 2.2 amps to play with the wilson watt puppy 7 speakers. I know that you have the 1.2 but they are close cousins (yours having more class a power and mine having more overall power but both being monoblock hybrids).
Anyway, I can assure you that the lamm and wilson combo is a great one. The mid-range and the vocals will amaze you. The icing on the cake for me is that lamm uses the wilson speakers at many shows where they showcase their amps. I mean if lamm thinks that wilson will highlight their amplifiers than I felt reassured it was the right direction to go in.
There are a lot of wilson bashers on the audiogon and they make hypertechnical arguments to support their claims. I concede that the speakers are pricey but it will work like hand in glove with the lamm 1.2. I even emailed lamm and they told me either the 1.2 or 2.2 would work great with the wp7.

p.s. I debated whether to get the 1.2 versus the 2.2 lamm amp but since I was going from a 300 watt solid state amp, I was a little hesitant to give up too much power and thought it would be the best of both worlds.
