Well I don't know if my post will be of much help to you but I have the DS212j. I don't have any DLNA devices, I'm using Audio Station with my iPod touch with the DS audio app and using the Apple TV 3 as the media renderer. I'm no audiophile but I can't tell any difference using this method vs. direct from a PC or Mac using iTunes to the ATV. Not exactly what you wanted to know but maybe it's a help. I will say the Synology is awesome. Once the drives are formatted, which for 5TB I let run overnight, I had things setup in less than a half hour. Visible from my Mac's, PC's, Roku (with Roksbox)...it truly works very well without babysitting or trying to figure out what it's issue is today. Very happy with my purchase up to this point.
