Srimad Bhagavatam's every syllable is a seed of transcendence. Therefore acaryas have expanded, drawn out; therefore hearing from acaryas is important.
Attentive hearing is the basis of liberation.
So in this Kali-yuga, if you simply chant or even if you cannot chant – because that requires little fortune — if we simply hear, that will also help us. So these centers are meant for chanting and hearing about Krishna. Simply this process, chanting and hearing, will purify our existence.

We should not be anxious to hear about Krishna for our entertainment or sense gratification, but for our PURIFICATION.
Faith comes by hearing Krishna Katha in the association of sincere devotees regularly.
The influence of a pure devotee is such that if someone comes to associate with him with a little faith, one gets the chance of hearing about the Lord from authoritative scriptures like Bhagavad Gita and Srimad Bhagavatam.
