Even though my VR-1s sounded completely different than the LSA 1s (nods toward Larry and smiles) the best amps I used with them were the Monarchy SM-70 Pro monoblocks. Smooth as silk, just a tad on the warm side, and plenty of power; I imagine they'd be a great complement to the LSA 1s, and it looks like Orangepotato has come to the same conclusion. Certainly worth a listen for the low price of entry.
