Do I have to use a streamer/renderer to play music from an NAS?

I apologize for the basic question. But, I can’t seem to find an answer online. I would like to put all my CDs on an NAS and play that music through my system. I have a Rotel RC/RB-1590 set up. I know some NAS boxes come with DLNA software installed, and I am looking at Synology because I read their software for finding and selecting music to play is pretty good. Eventually, I will probably end up with something like a Cambridge Audio CXN or 851N to stream tidal and digital radio, as well as the music on the NAS. But, do I have to have the Cambridge or some other device to just play the digital music from the NAS to start? I would like to do the purchases in steps so I can get better units as I can afford them.  Also, any advice on alternative solutions would be much appreciated. Thanks.
