I’ve used Vision strings on my Gagliano for the last few years. My ”violin doc”, Torbjörn Zethelius recommended that brand. Last time I visited his ateljé, he asked me to try a new brand, Warchal brilliant.
Now I’ve compared those two brands. Warchal gives a very big sound, which is great for a soloist, but Visions Titanium Solo strings also sound ”big”. The thing that makes me vote for Vision, is that the sound is so warm and round.
So, Warchal is great and Vision excellent!!
