Best amp for Sonus Faber

I have owned a number of Sonus Faber speakers and my keepers are my Guarneri Homages. My amplifier driving those is a John Tucker modified LSA Statement.

Another great amplifier I owned and I understand was used by Sonus Faber to voice some of their speakers in the past was a David Berning ZH-270.

The ZH270 is a fabulous amplifier and still a bargain. Don't let the age of those put you off as their design and reliability is outstanding.

Great discussion and thank you for all taking the time to answer.
 

I fell in love with the 509Z after a few listening sessions with various integrateds and for me it was a massive step up in clarity and control from a Michi x3, S2  

I do want to do a comparison with T+A, Accuphase Es and McIntoshes - both solid state and perhaps a 352 with a tube front end, but the tube life is not one I’m convinced is for me.

Until you share what specific improvements and sound characteristics you’re looking for this is just a crapshoot.

I've used big Chord SS and it was spectacular and now an Audiomat Solfege Reference 20 with my SF Guarneri standmounts. Not a big sample size but do know I didn't like YBA and Naim electronics. The Chord and Audiomat really manhandle the drivers and provide the impact I prefer. Just my experience
