i don't know about these specific model sonus fabers, but in my experience i have never heard a bad sounding pair of SF's whether they were extremas, guarneris, or electra amators (and the EA's were poorly set up at an audio show, which was a double surprise). OTOH the price on these compared to the $24K amati homages is a bit of a shock to say the least, and they are kind of "flashy"
looking over the previous lineups. however, i admit my biases are in favor of a smoother richer sound and i can understand people preferring a more "neutral" sound instead.
