I'm running Symphonic Line Kraft 250s that are Class A. They get warm but not hot - and actually run cooler than the Class A/B Plinius SB-301 stereo amp they replaced in my system.
The Symphonic Line website lists Sonus Faber as one of the manufacturers that use SL amps to design their products. They are not as well known as Pass here in the U.S., but they are in the same league as other top European amps like FM Acoustics, Gryphon, Dartzeel etc.
