While late-model Wilson Audio WATT/Puppies -- series 7 and 8 especially -- were good to go with the ML2s and ML2.1s, Vladimir Lamm doesn't recommend the ML2.2s for use with Sasha W/Ps (Lamm M1.2 Reference hybrid amps drive them gorgeously, however).
While I wholeheartedly agree about the M1.2s and Sasha since I've lived with that combo, the Momentum monoblocks+Sasha has redefined that concept for me.
It is THE pairing to beat now, IMHO.
