Hi! These are my headphones:
HD600- Both, classical and rock. Better for rock. No eq.
DT880 (600Ohm)- Only for classical music (equalized).
K702- Only for classical music (bass port mod).
HE400SE- Both, classical and rock (equalized).
SRH440- I love them for everything! No eq
SRH840- Just...
Since I love the 440 I just ordered the 840 (both without "A") for €89. Do you think I will notice an improvement in classical music? I guess I'll have to reduce the bass a bit, right?
