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.

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.  

I'm now in the same position as the OP, having just purchased a pair of new Olympica 3's, on a great, year end deal from a dealer that badly needed to move some product. So now I need an amp too. 

markmendenhall, can you describe a bit more about the sound you got from the X150.08 with your O3's? My understanding is that the Pass 08 series is more dynamic and  palpable than the Pass 05 Series, but lacks the richness and fluidity of the 05 series midrange.

This is my first Pass amp so I can't compare the .5 vs the .8 series.  Mark at Reno HiFi is a good source to consult with.  I find nothing lacking in my .8 amp.  Better bass than the A21 or Bel Canto REF 1000M monos.  SET like mids, huge soundstage, delicate and extended highs. I'm investing in additional power supplies for my pre amps at this time.  I think my amp cravings have been satisfied with the Pass X150.8.  
J have s custom dual mono block  Pass Labs  F-6 which is 
50wpc pure class A  and stable into 2 ohms.
Do the Math depending how loud you need it Class A will bring a Tom more grip
Then a AB amp of 2x the Power.  90db@1 w. Personally 90db  at output 
Is ear damage level and the speaker will use roughly over 30 wpc on driving music.  Many people think  ,I will need just 1 w to get 90db output.
There's a lot more to the equation. These speakers dip fine to about 2.8ohms 
At their lowest. The model 3 ,is actually slightly more efficient then the 2 .
