What Amp with Sonus Faber Olympica 3?


Greetings....Curious to know what amp are you using with the Olympica 3?  Seems they need some juice at the 80-120Hz region and dip to 2-ohms so I understand it takes some current to properly drive. Just sold a ARC Ref110 and looking for a replacement. Short list:

Pass Labs 150.8 or 30.8
Audio Research Ref 150/75SE
McIntosh MC275
Primaluna EVO 400 

Preamp is a Primaluna EVO 400. Listening room is 16x16 with vaulted ceilings and listening volume level can top out around 90db give or take a few  :)

“Which Classe Delta?”

I believe it is just called the Delta Stereo amp and they were using the matching pre amp. Very nice sounding setup. I think it is $12,000 though. Class A for the first 12 watts.

Are you referring to the Olympica 3 or the newer Olympica Nova 3? I have the newer Nova 3 and use the Audio Research Ref 75se. My room is 13x13. I listen at 80 db or less usually. The meter on the amp never goes over 1 watt. I think the newer model is easier to drive and more efficient.
Happy listening.

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...
