I have a pair of Amati Anniversario's with Guarneri's as rear channels with a Rel Stentor 3 sub. They are powered by ARC reference 210watts monobloks and ARC ref 110watt stereo for the Guarneri's. I use a Krell s1000 as processor. For the moment I have decided to run the system in phantom center mode, it processes all center information through L and R. Since it sounds so magical, I have not felt the need to get a center, I guess if Sonus Faber released an homage center, I may try it. But at the moment it is just amazing. Voice is handled very well by the Amati's. I am around 20 feet away from them and they disappear. High resolution and very vivid. After many auditions with SS amps, I just could not resist the Audio Research ref monobloks. I am very happy with this system, both for music and home theater. blu ray movies are intense. Concert Dvd's are lifelike.
