What are all these different output jacks for?

I purchaced a CEC 3300 cd player. The Anolog Output section has Analog Balanced output jacks Right and Left and also RCA jacks R and L.
The Digital Out section has Coaxal, Optical and an AES/EBU. ( I assume the digital out would be for using a DAC).
My question is what are the uses and functions for all of these output options?
I will be using a Unison Unico integrated amp. and Meadowlark Ospreys.
Thanks
