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  :)

@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? 
Spoke with Mark at Reno HiFi. He recommended a Pass 150.8.  Looks like I'll be getting a 150.8.  
@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. 
@jjss49  thank you for that comparison and I suppose you are correct. The 110 with more tubes had better control but still not enough as also holds true for the Ref 75SE.  I have read a couple of Olympica 3 reviews where the reviewer used a Ref 75SE and was very satisfied with the combination however, did not really comment about lack of bass. But we can see the O3 needs current down low and typically tube amps can't solve the low impedance issue. 
Why Tom why do you hate ARC so much haha?  But I think it is clear as mentioned above I DO understand the O3 needs CURRENT :)
Thanks. I’m excited to get it jjss49. Should really open these speakers up. I’ll report back in a week or so. Thanks again everyone for the advice and these threads are always fun. Well not for Tom 😆😜

I am enjoying the 150.8. It has taken some time to grow on me but my speakers needed some break-in as did the preamp.  Things are smoothing out quite nicely. At first I wasn't sure I was going to warm up to the amp however, as usual everything needs to settle for awhile. Changing the front 2 tubes on the EVO 400 preamp to Mullard CV4003 really helped the focus and take some edge off. The stock tubes aren't bad but this is where I was experiencing unwanted energy so to speak. The 150.8 has PLENTY of power and the needle doesn't even move so I am staying in Class A. Lots of depth and layering  :)
