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.

I run a  Synology NAS that I keep on the first floor on my wired network running CAT7 cables and through a few gig switches. I have two stereo systems the main uses a PS Audio Directstream and one a Perdfectwave DAC, both connected to the network. All the computers on the network have JRiver installed as well as a tablet so I can control from anywhere. The software seems to work well (Windows based computers) and the SQ on either system is more than acceptable. Have not fiddled with ethernet cables outside of upgrading from CAT5's as I feel it is just data at that point and not sure how different cable would make the data better.

I have also a Synology NAS, an he is wirelessly connected to my Logitech Squeezebox Touch ( little, but very good) and this is digitally connected to the DAC of the Luxman D06. On the Pc.,i use the app. IPeng. (To save the music). Along my iPad,i can play my recorded music.
to Steve:
Why do you advise against *lossless* formats like FLAC/ALAC?

They are, after all, lossless, and after reconstruction are identical to RAW. And, I have compared and heard absolutely no difference. I admit i have not compared many times or particularly carefully since (danger will robinson!) i knew what the result would be :-)

No, on low powered computers or slow disks i could see it causing more power noise or even jitter/errors, but that would show up.
On re-reading your post i wonder if there is a subtlety in it, you actually say "avoid ripping to ALAC or compressed file using itunes". Is itunes somehow the problem(how?) or ALAC, which, after all, is lossless (mostly DPCM)??  TIA

I really appreciate the kind respnses. I am still a little confused.  Lukaske, it seemed from your response that your NAS is connected wirelessly to a Squeezebox, which I assume functions like a tablet, and that the NAS is then connected to your DAC, with no other renderer.  Is that correct?  If so, which Synology do you use? That is how I am considering setting up mine for now, adding a good streamer/renderer as I save up more money.
kumakahn the Squeezebox is a streamer/renderer it sends the digital signal to the Dac. That is how most streamers work I have an Auralic Aries Mini my Synology 214-play is connected to my modem/router and communicates wirelessly with the Mini.
