I would be very grateful if the experts on this forum could help me make some equipment decisions in my effort to network a Mac, iPad and a couple iPhones into a NAS that will connect with my home theater. My overall objective is to be able to access my picture, video and music collection on MAC and store on a NAS via Plex then run the NAS to an OPPO 205 Blu-ray player to a Yamaha 5100 preamp for viewing on a 75” Sony 4K HDR TV. I have an extensive collection of Blu-ray concerts and movies that I would like to rip and store. Don’t know much about Plex other than it will organize all of the media for easy access and playback. I’m running 7 higher end speakers and 4 subs so I’m not looking to lose anything sonically. Am I on the right track with a NAS and Plex, hooked up thru the OPPO Blu-ray? I was thinking 4 bay, fast CPU, 4 Ram, HDMI output, adequate Ethernet ports etc. Help???
