Tube amplifier to power Sonus Faber speakers?


I recently purchased a new pair of Sonus Faber Olympica 3 speakers. They are 90DB and a 4 ohm load. I've always preferred tube amplification and am finding it a challenge to identify a good match for these speakers. I'm not a kt88 fanbut rather 300B or something of that ilk. I tried an 845 based amp but found it edgy and limited in power and dynamics. Any suggestions from Sonus Faber owners is most welcome.

I would like to suggest ARC as a tube amp to consider. FWIW, I believe ARC is currently using SF as its reference speakers when checking the performance of its gear.

That should be no surprise since SF and ARC are member companies of the Fine Sounds Group. This may be a leap of faith on my part, but that might permit an inference that ARC and SF make for a good match.

The specific ARC amp you might want to consider is the Ref 75. This pup has garnered quite a bit of favorable comments. I own its big brother, the Ref 150. The two amps share similar circuitry and probably share a similar house sound.

Not sure how much you want to spend, but the ARC Ref 75 is a keeper.
I use the Audio Research VSi60 (50wpc) tube amp with my Olympica II speakers and find it to be an excellent match. I typically listen with the volume between 30-40% of full on and it can play quite loudly if I turn it up higher. The Olympica III is more sensitive than the II so unless you'll be using them in a very large space or typically listen with the volume really high, the VSi60 might be a great option to consider depending on your budget.

Ready for Challenge .... great .... That is the right spirit to invest endless time to try to match a mismatch... 300B with 90 dB amps... What a great idea. ... Ever saw a Duck with teeth? No? Don't worry, you will find that one sooner ...
Good luck -:)
I'm using wyetech lab ruby 211 with RCA tubes on sonus faber guarneri homage ,a friend is using the same amp but wyetechs 300b version, on his amati futuras ,you should get wyetech labs onyx for the olympica
The Sonus Faber dealer here in SW FL uses fairly large Audio Research tube mono blocks (sorry, I can't remember the models) to power his Olympicas. The sound is top notch.
