I am also looking at purchasing a Hermine and have had a chance to play 3, 2 new, one a few years old. The strings are a type of carbon fiber, I was told by my teacher that they have a slightly different feel, are more costly but they rarely break. The previously owned model I played had a developed rich and beautiful voice. The new ones were also lovely, but I always find it helpful to hear one that has had time to mature. It has 34 strings starting 2 octaves below middle C, the same as most 36 string harps minus the top two strings.
I am not sure where you are located but I know Sue Carole DeVale, a Harps International Rep, carries them…maybe she could play one for you on the phone or skype?
