Without knowing more than your speaker specs I'll concur with the Atmas or used Lamm ML 2.1s. The Atma-Sphere MA-1s are neither inherently warm nor cool, they are very quick with extended highs and taut bass and music through them has a clarity of transparency that makes them worth a listen. The best rendition I've heard of female vocals has come through Atma-Sphere gear. The M-60s and MA-2s sound very similar to the MA-1s.
