I have experiences with Amati Anniversario and Usher BE-20, they are very different.
Both have excellent top end, they are both sweet, extended, and quick. Midrange is where they are most different, Usher is sharper, more define, leading edge attack is more defined, but decay is faster. Amati is sweeter in midrange, has longer decay, not quite as detail, but fuller and more body.
Usher will require more current to control the bass, but if you have the amplification to drive the Usher they do reward you with plenty of bass weight with definition. Amati bass quantity will be less, but should be sufficient for most though you do have a very large room.
