Quote/Summary/Review High End Audiophile Magazine My wife was on to something special when she noticed the clarinet playing over the Dynaudio Contour 3.0, and I have to thank her for it. This loudspeaker does so many things sonically right that it has become my reference for a floorstanding, full-range, three-way dynamic system. I strongly recommend it for any high-end audio system, for both the audiophile and his or her spouseOriginal packaging and serial number!
