Congrats Joe! The Sonus Faber Stradivari is the finest loudspeaker that I recall hearing. It stood out as the most musical, most dynamic with the best presence that I've ever heard.
Two summers ago my wife and I were in Scottsdale, AZ for a visit and we had a free Sunday. Ended up at LMCHE and spent three hours or so alone with a fine salesman (Mike?) that demo'd at least ten different setups in as many rooms. Those Strad's were setup in a room with Mc amps (most rooms were Mc but I'm not sure what exactly was powering the SF) and were positioned against the longer wall with the seating position in the shorter dimension. I'd guess the speakers were about 10-12' apart and the seating was maybe 8-10' back from their plane.
I don't know if I've ever heard a more realistic representation of what music is supposed to sound like than that experience.
Enjoy them kind sir, they are magical.
