"OpalTitan strings are fantastic! I love their rich sound . . . simply velvety, rich, grandiose tone. They are easy on the fingers. These strings remind me of gut strings that I used to play back in Europe, but without the inconvenience of constant tuning and tone crush. I'm a total convert to the Opal strings." 

Note by animato Strings:

We found this string set to produce one of the sweetest sounds. It is a delightful set of strings for the chamber musician and orchestra member.
