Does your system provide a non-fatiguing listening experience? Do your ears ring afterward in a quiet/noiseless place? How far from the speakers is your listening position?
I'll go out on a limb and say that if your system is not very resolving and causes fatigue after less than an hour into the listening session, and you continue to listen - then yes this level is not good for your hearing (it's probably not good for your hearing even if a system is non-fatiguing - 'causing one to listen longer - but at least it's perceptively enjoyable).
