What makes strings sound "sweet"?


I have always wondered about this. If you listen to many recordings of bowed string instruments, then you know that the upper registers can sometimes have a sweet tone. I define this by what it is not - edgy, brittle, dry and rough sounding. It is smooth and inviting. I used to assume this was due to rolled off highs or an emphasized midrange, but I am not so sure. It varies by recording, or course, but I have often wondered what, in the recording or reproduction process, causes strings to either sound brittle or sweet. Is it the acoustic of the original recording venue? A frequency balance issue? I would love to hear from those who might know. Thanks!

Thanks, all. Very interesting replies. Kijanki - thanks for all the info, but my OP specified "recordings" of bowed string instruments. Music is, for me, stricktly a spectator sport. :-)
Agreed for the most part, Mapman and Kijanki. I have some recordings that have sweet string sound on almost any system I play them on - even my all-original factory-equiped Subarau car stereo! OTOH, I some recordings that have screechy, dry sounding strings on every system I play them on. So, IMHO, this seems like a more recording-dependent issue than some other sonic traits. And, Mapman, I have heard both of these traits on vinyl as well as CD.
