The four string sound is quite beautiful, with decent projection power, suitable for the orchestra's first violin.

The G and D strings performed surprisingly well, especially the G string, which outperformed Dominant and D'Addario Ascente in terms of high grip clarity.

G D string has a warmer tone and less metallic sound compared to A E string.

The A-E string has a cooler sound sensation and a faster response, surpassing Dominant (slightly better than D'Addario Ascente).

The performance of string A is slightly inferior, and the volume is not as concentrated as G, D, and E. Personally, it feels quite silicone like.

The E-string is bright and stable, surpassing Dominant and D'Addario Ascente. It performs well in overtones, but its disadvantage is that it may produce whistling sounds during strong playing, which is not suitable for people with sensitive hearing.

Main technical features and specifications of Vision:

Core material:

E-string (e ² mi, VI01): Carbon steel core, tin plated, providing bright and stable high notes.

A-string (a ¹ la, VI02): synthetic core, aluminum winding, or optional carbon steel core chrome winding to increase durability and response speed.

D string (d ¹ re, VI03): synthetic core, aluminum or silver winding, enhances tone richness.

G string (g sol, VI04): synthetic core, wrapped in aluminum or silver, providing deep bass performance.
