tot the types of violin strings used is one of the major reason for how bright your violin sounds, no?
different string brand also counts... even same brand, same type of string, they have different types quality which produces diff type of sounds

sorry just writing what i gathered from the articles i read... no personal experiences as only change 2 strings in my violin.
but definitely heard some differences in the dominant g string compared to my original g on my cina violin....
not sure the dominant g string is defective or what but a little slow in response....
as for the second string that snapped, the e string, the dominant e really sound better than the original e string which was a little harsh ...

haha.. again my own opinion la..
some of the info i quoted from some sites :
types of strings matters ..."
Gut-core strings have their own unique sound, which is very full and complex with lots of overtones. "
"Many (but not all)
steel-core strings have a tendency toward brightness. The sound is usually clear but simple, with few overtones."
synthetic core - "a string that sounded like a gut-core string but didn’t have the disadvantages of pitch instability and slow response. These strings use a core of perlon (a type of nylon) wrapped with silver or aluminum. "
e.g. synthetic core strings and sounds produced by different brands"Thomastik-Infeld Dominants ($54–$58), the original
synthetic-core strings, are still top sellers. The sound is brilliant and responsive, and these strings seem to work well with many different instruments."
"Pirastro’s first response to Thomastik-Infeld Dominant strings (see below) was the Aricore ($37). This string has a dark, warm sound, but can be dull and rather dead on some instruments. "
" The Infeld Red set has a darker, warmer sound, and the Infeld Blue is more brilliant. "
