I think these are good student strings, though they really are (to my ears) lacking in warmth.  The official term is "bright."  I think these strings approach the line toward "harsh" on certain rigs but they don't quite cross it.  However, they are certainly a step or two above the no-name strings that come on violins these days (and indeed, lots of student violins are starting to get speced with Preludes out of the box) and certainly represent an upgrade.
