Congrats - I have a bunch of Oppo players, including two 103Ds. One is in the main system just for video and then I have one in a back-up HT for video and have hi-rez music files (including DSD and multi-channel DSD) on an attached hard drive (as well as my NAS) that I can play music from. The Oppo (Media Control) App is free for either IOS or Android and lets you select the files from an attached hard drive and play them from your tablet or phone.
