The Superior set sound warm, round and powerful from the first second after winding up the strings. They are very well balanced and rich in overtones. They support full forte and deep piano colors and they are very projecting and responsive. Superior strings are perfect for chamber music, orchestral playing and solos. The strings are very long-lasting which make them one of the best price-performance ratio in the market. The G and C strings are very powerful and the sound is nearly Spirocore like.With the A and D Superior you have the traditional warm and brilliant Jargar sound but more of it compared to the Classic A and D. The G and C strings have been created to match the more powerful sound of the Superior A and D. All in all you have a very well balanced set.
