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.
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.
