I disagree. Even with the poor sound quality of the video you can hear that Bell's tone is much fuller and richer than that of an amateur violinist's. You can also tell that his technique is impeccable --- those Bach pieces on the videos are amongst the most technically difficult in the repertoire. Most amateur violinists will blat wrong notes in those pieces. Bell's phrasing is also much more polished. I suppose if people haven't been exposed much to classical music it might not be surprising that they can't identify real quality.
