Ah, classical music. You'll want a neutral headphone - it's the only way to go. Of the headphones I've heard, these are the best cans for classical music.
Imo, there are two kinds of people -
1. those who want to relax and enjoy the overall classical performance
2. those who enjoys the tiny details in classical music.
Shure SRH940 - very good for solos (especially violins), not recommended for orchestras (bass is lacking and is below neutral, timpanis almost disappear)
The big TRIO:
- HD800 - massive soundstage, for full scale orchestras it's a 10/10 (1,2)
- DT880 - Very involving with classical music. I call it classical listening pleasure. (1)
- HD600 - One word to describe is it perfect. I can feel the bow scraping against the strings of the violin and the details is just overwhelming. Take out HD800's soundstage and you have the HD600. (2)
I belong to group number 2 and I preferred the HD600.
