The Superior Cello set sounds warm, round and powerful from the first second after winding up the strings. They are very well balanced and rich in overtones. They both support full forte and deep piano colors and they are very projective 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. With the Superior A and D you have the traditional warm and rich Jargar Sound but more of it compared to the Classic A and D. The rope core G and C wounded with Tungsten 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. The Superior A and D strings come three different tensions Forte, Medium and Dolce, Superior G and C only come in medium tension.
