Yes, I found that Neutron definitely works better with SMB, than DLNA. But both work fairly well. The problem with most things like VLC or Fiio Music Player is that they really hit a wall when you have enormous network music libraries. I've moved virtually everything to the server and hitting 50,000 songs/5,000 albums, mostly 96/24 and DSD, and things really start to fall apart for most of the software/hardware out there. If there isn't any substantial improvement in the next firmware, then I'll definitely sell my M6 and maybe try the Hiby R3, or maybe a better Android phone that supports LDAC (to use with my BTR3, or even my Alpen or Andes). I'll look into SambaPlayer. I don't remember trying that one.
