I've been a victim of buying speakers based on what appealed to me during a short 30-minute demo at the dealer. I have found that SF speakers, at least the ones I auditioned (Olympica line; old and Nova) are not that impressive during short auditions since nothing stands out. B&W on the other hand will grab your attention immediately. Once you take them home, YMMV. SF has this intimate, delicate presentation that can only be enjoyed in your home while sipping a glass of whiskey. I disagree with the poster who said that SF are only good for classical music. They are extremely good for jazz, blues, vocals, classic/soft rock. Although, if you like to rock out, scratch SF off your list. They're not bad for serious rock or electronic music, but definitely not their forte.
Just to be clear, I'm not suggesting that one is better than the other, just that auditions, while better than none, can sometimes be misleading.
