It is indeed bassy IMO if properly driven. Even for Because You Loved Me by Celine Dion, just by connecting to my cheapo Aune T1 I can feel the bass strength, but in a good way. But with Xduoo TA-01, the music become more romantic, relaxing bass... Some say V-moda 100 is a good bass oriented can, well they are overly bass to my ears.
The HE500s are not considered super bassy but they are so so much bassier than the HD600s and this is driving both through speaker amps (I've never heard the bass go so deep and clear on the HD600) but still I wouldn't called the HD600s bassy through any stretch of the imagination
