If it shares the same tonality as the Sonus Faber Amati Futura speakers, then they're a little on the warm side. If I'm correct a more neutral sounding integrated amp would suit best.
Also check out WHF reviews, might give you a steer.

I recently purchased secondhand Atoll IN100SE (with integrated DAC) and I was blown away. One of the most natural sounding amps I've heard. A little forward but also neutral, great throughout and wide sound stage.
If you can stretch your budget, consider also the Hegels, Primare, Roksan or maybe the Audiolab 9000A.
