I guess I consider myself somewhat an "audiophile". Recently I loaded all my CDs, SACDs, 1080p & Blu-Ray material onto my Plex Home Media Server. Throughout my home, Plex delivers my music content via FLAC files and movies in 1080P, TrueHD and 4k beautifully. What are most people using as their music/movie source and why? What's all the stink about having a DAC? What are the advantages/disadvantages of using a DAC?
