Old thread but I have an N-05XD and have questions for other owners.
I first used the N-05XD with a dedicated music server I have (high-end custom build) that runs Roon. It didn't sound great. I never knew how limited it was until I turned off Roon-Only mode and ran the Esoteric using Soundstream app and an external 4TB SSD (via USB). This setup is night and day better but I know that an external SSD connected via a USB-C cable is still sub-optimal. In fact, as strange as this sounds, the sound quality actually improves/declines based upon how much the SSD is being accessed; better at the start of the listening session, not as good at the end especially if I am shuffling songs. I'm no computer expert, but I'd guess it's got something to do with the internal heat of the drive. It's the best Samsung I could find.
I'm thinking going to a NAS would be better. I have room on my switch to install one about 60 feet from the Esoteric (which is also connected to the switch through a wired ethernet connection). Any thoughts or suggestions on what I should buy? Thanks very much.
