Synology DS416j to Android

[ChuckM6421]

Hi Simon, all. My first post and intrigued, but stumped.

In simple terms I have a large collection of 24 bit flac files stored on a Synology DS416j that I want to play through a repurposed Android phone (Droid 4 rooted with the LineageOS) possibly using the Neutron app.

In more detail: my DS416j is networked (wired) to an Asus RT-AC68U (running the Asuswrt-merlin customized version of the Asus firmware). My Droid4 has an excellent wireless connection. I may also want to use an LG V990 connected to a Denon receiver to make use of it's internal 32 bit DAC.

In either case the goal is to play the flacs on an Android.

I've been stumbling around the forum here, installed MinmServer on the NAS, MinimWatch on my PC and am left to wondering how I bring Android into the picture.

I'll accept I may be going in the wrong direction here for a solution but I'm tired of fooling around with the DS Audio thing. Whatever I can get to work still downgrades the quality of the music files.
