This is a slight tangent but I just replaced a pair of Sonus Faber Concerto Domus speakers with some Harbeth 30.1 speakers
I tried out a bunch of different speakers including the SF Olympica 1 and the Devore O/96 and none worked for my wife and me. I put the Harbeth speakers in and we both agreed that they had more of everything that we liked - my wife's comment was that for the first time she understood why someone would spend money to upgrade speakers. I wish that my space was big enough for the 40.1 model
