I would consider getting rid of one pair of my Kappa9 speakers for the Stradaveris....but l would need a listen...as far as Sonus Faber goes...there silk tweeters and paper midranges just have such a great sound, warm,seductive, non irritating.....one guy described most modern speakers as being "hyper real"...l know Sonus Faber delivers because my wife and I have coffee every morning in my 2 channel room....we will talk about the days schedule and she will leave after about half hour...l noticed if my Cremonas are on or my Accordos....she will stay in the room until l turn off the system...That's pretty cool 😎
