How to use my Cambrige Audio Stream Magic 6

Hi,apologies in advance for my advanced state of ignorance in all things hifi-I bought a Cambridge Audio Stream Magic 6 on Ebay c.6 years ago -.I bought the Bluetooth Dongle also on Ebay.I have only taken it out of the box,but haven't set it up.Do I need an amplifer for it? If so,would my 30+year old Rotel AM/FM Stereo Receiver RX-850A be ok? I am currently listening to my cds which are all in my Bluesound Vault 2,via ethernet and through Ruark mr1 mk2s-All wified and and hardwired.Does this count as hi fi? Thank you
