Have been a fan of Sonus Faber for many years starting from my first pair the Electa Amators then switching over to the Guarneri Hommage which I have had for a number of years now. You can guess this from the serial number I mentioned previously no. 13!
I have heard most SF speakers as they have been progressively introduced, including the Cremona (light brigher sound), Amati Hommage (which was like my Guarneri but fuller +deeper), and Stradivari which was amazing in all respects.
Have not heard any other newer versions but I must say I prefer the look of my Guarneri compared to the Momento.
Will have to track down a dealer to take a listen!
