Every time I tried different brands I always ended up going back to Dominant. They are good quality neutral strings, whihc means that they are bang in the middle in terms of color and tone. They don't make your violin sound warmer or brighter, they don't add any specific character of their own, they are perfectly balanced accross the tonal spectrum, which is the reason why there are so many Stradivari or Guarnieri violins out there strung with Dominant to let the natural tone of the violin shine through. They'll sound decent on a decent violin, beautifully in a beautiful violin etc. Only downside is the dreaded e, which is almost always replaced with a less harsh sounding e (I personally use Pirastro Gold Label)
