Massed strings and large choral groups


A longtime audio dealer and fellow audiophile told me that massed strings and large choral groups are two of the hardest things for a system to reproduce. Do you agree?

Frogman, do you sing in a choir or play an instrument? You said you took part in a Mahler performance.....
Whart, I play clarinets and saxophones. In that particular performance I played the bass clarinet/C clarinet part.

I agree, the 4th movement, Chorale, from Beethoven's 9th is a challenge that my system struggles with and always frustrates me when I listen.
