Finally got the Synology DS218+ with dual enterprise WD/Hitachi 10TB HDD for 5TB of music and redundancy in additional to existing Cosair 512GB thumbdrive to the rear usb3.0 port of the Omnia S1 and a 128gb sdcard via usb adaptor to the allo usb bridge signature running moode OS.
Added the following findings or my limited experience which are perhaps already known to many but I am really a noob in streaming, NAS etc.
- moode dlna server is a miniserver and dsd, dff etc. hires files does not show since not supported
- cosair usb thumbdrive to omnia may not be detected even if rebooted .. I need to remove and reinsert for it to show up as omnia server and few mins only for 512gb to appear for playback
- playing same music files in cosair thumbdrive is discernibly better SQ in my system as compared to via NAS .. expected to me since addtional 2 more ethernet cat 8 cable and a consumer grade 8 ports switch
Updated photos with Synology and highly manageable bubbleupnp app page showing 2 renderers/player of omnia and allo usb bridge signature and the 3 servers/library .. glad singapore distro of Jye and my SAP expert friend helped thus far.
