Optima Violin Goldbrokat 24K Gold Premium E-Strings The new Optima Goldbrokat Premium Gold E string offers the same performance as the original Goldbrokat violin E string, but with enhanced features. This Gold E string utilizes a new steel alloy with an extremely uniform and smooth surface, providing increased durability. Furthermore, the string is plated with 24K gold, leveraging Optima's decades of experience in producing gold strings. The sound of this string is bright and powerful, similar to the original, but with a warmer and mellower tone and improved projection. The compatibility of this string is exceptional, and it pairs well with various brands of violin strings. Personally, I prefer pairing it with Pirastro Evah Pirazzi or Thomastik Infeld Dominant.
