I would suggest the McIntosh MC452. I use that amp with my Sf Auditor Ms and it mates well. I will keep the amp but update the speakers to Sf GM or Evos someday.
Amplifier for Sonus Faber Guarneri EVO's
I have a pair in Walnut on their way and I am doing a complete reset of my existing system. Very curious which amplifiers people have had great experience with while paired with the EVOs. I am open to both tube or solid state and would also consider a high quality integrated. My source with be Bryston BDP-1 and BDA-1. I like the option of running balanced, though single ended is fine too.
