LTig, I see you have a working solution running a DLNA server on your Synology NAS, streaming to your Sigma SSP's DLNA renderer ... but gapless playback does not work.
I understand that successful gapless playback with DLNA depends on the interaction between DLNA controller and renderer (nothing to do with the server) and Google tells me that the Sigma SSP renderer will not play well in this regard -

My preference is Music Player Daemon ... but this usually requires some command line Linux skills to set up.
LMS/Squeezelite via piCorePlayer is popular - for this you need an LMS control app on your phone such as SqueezePlayer or Squeezer.
Or Volumio or Moode Audio are good options - these are controlled from any web browser.

Yes, that's a good option. Configure the rPi to mount the NAS as a CIFS network share, then run a music server of your choice on the rPi.I might get me an RPI4 which mounts the NAS audio folder to circumvent the DLNA server.
