exile_ken, yes now it is running Lightning server and LightningDS.
I have approximately 60,000 tracks from various sources (my different rips, tracks purchases, hdtracks downloads, etc) and library is very manageable. I did not measure, but it took less then an hour for sure to load and index it from my NAS (Synology 414 with 12G of drives). Integration with Tidal is pretty dicent (for example when I am search for track in my library search terms remains when I am click Tidal, which is very useful). Tidal sounds way better now then with OPPO app.
There are some quirks (not all album artwork shows up, I have to figure out why) and it is by no means a swiss-knife jriver (I have to try jriver+BubbleUpnp I used with OPPO) - but still not bad. I am running 5.1 beta, and having my CUE-based rips plays without pauses is great (OPPO could not).
I am running LightningDS on new ipad with 128G memory. As a convenience it worked I would say B- so far, but as playback quality concern - A+ (at least compared to my PC, OPPO or previous cheap streamers, which were even worse). Is it femto clock, is it AES/EBU vs coaх I do not know.
