Old post, but fwiw, I just paired my SF O3's with a Pass Labs X150.8 stereo amp. This amp elicits more out of the speakers top to bottom than any other amps I've tried. Excellent match. Sorry for being a bit sideways of the specific question above.
Which Amplifier for Sonus Faber Olympica 3 Speaker
I own a pair of SF Olympica 3 speakers and have narrowed my choices to 2 amplifiers. My tastes lean toward the warmer richer side of the fence. The Hegel 300 or 1 of the LFD amplifiers. On 1 hand the LFD is lower power but quite balanced. The Hegel is approximately the same price but has 250 wats of power plus a built-in DAC. My speakers rquire some power at 90DB efficient but its a 4 ohm load. I have heard the Hegel but with Magico speakers. It sounded good with nice detail and never tipped over the edge. The LFD is playing on my speakers now but drawing comparisons is difficult given different speakers. Any thoughts re these 2 amplifiers is most welcome.
