I bought these strings for my second violin. I had Evah Pirazzi golds on my main violin and liked the sound very much - but the Larsen Virtuosos were better. I now have Larsen Virtuosos on both violins.
The Larsen Vs sing on the E string like no other string I've ever tried (although there is a slight metallic sound on the open e for about the first three hours of playing, then it goes). The Evahs sing, too, but not quite as much. Both sets of strings are poweful and have lovely rich overtones - maybe the Evahs are slightly warmer and the Larsens slightly smoother.
The Larsen G and D strings are marvellous - deep, clear, throbbing, rich. It's wonderful to have a rich sound on the G string that is clear, too.
The A string is sweet and powerful.
Both sets of strings are excellent but the Larsens, in my opinion, are better because they are easier to bow and easier for the left hand. I can play better with the Larsens - it seems like a miracle, as though my playing has risen to the next level. The sound is full and rich and thrilling.
