Mpit's comment is in line with my experience. Try as I might, massed strings on a large number of my favorite recording were a problem with my Wilson's. Peaky mic's, mic's to close, mastering issues, sunspots, who knows? Still, if I wanted to listen to Bruno Walter, forget it. But Refference Recordings, Sheffied's, Harmonia Mundi, etc. sounded fine. The string edge on too many recordings finally caused my to look elsewhere.
For the longest time I couldn't decide if the Wilson's had a peak in just the wrong place, a violin, or if most classical recording engineers go for excessive detail. I finally decided it was a little of both.
If you want sweet sounding strings, the old Wilson tweeter isn't your best bet. I suspect the new silk tweeter will be better. But with rock and jazz, the issue I had with Wilson was immaterial.
