What Amp with Sonus Faber Olympica 3?

tube amps really don’t like to see impedances 4 ohms and below... arc handles them better than most... if you have sold a ref 110 feeling it was lacking i don’t see how a primaluna or ref75 would do the trick

i think solid state power amp is where you need to go... you've got plenty of tube-i-ness in the pre stage as it is...

@woodman2  referring to the Olympica 3 not the newer Nova 3. From my understanding the Ref75SE is a bit warmer than the bigger Ref110/150 brothers? 

@jjss49 as far as the Ref 75SE I figured with the beefed up power supply and KT150s it would have sufficient power to push the O3 and sound lovely also. 

@samzx12

don’t think so... 8x kt120 in ref110 vs 4x kt150 in ref75se, through same transformers, even with slightly beefed up power supply

kt150 draws 20% more peak current than kt120 via datasheet (see link above), nowhere near double... and that assumes the power supply can deliver it through the 150...  so double the number of kt120's will still be 70-80% more powerful in transients -- thus i would expect that the ref110 will push and pull harder, greater grip, greater current, esp. with impedance low @ 2 ohms with difficult phase angles in bass region frequencies of the speaker ...

I might be comparing apples to oranges, but FWIW, I tried a GSi75 that took KT150s with Olympica II. The sound was impressive but it just didn't exert much control over the woofers.
