Yes, you can run the microRendu without a NAS in some setups, but most don't. Part of the beauty of it is that it's like a Swiss Army knife, so you can use it with NAS running Mimimserver(free) and control your music on tablet with free apps like Lumin(which I also use & love) or Linn Kazoo. If you prefer you can run HQ Player on your computer platform of choice do digital EQ,etc and use the mR as a network audio adapter. If you've been a Squeezebox guy, you can run LMS(free) on the NAS or a computer and use the Squeezelite(free) app for control.
One of the benefits is getting a full PC or Mac computer and its associated noise out of the listening room and galvanically isolated from the dac. While some would argue "the mR is a computer", that's true but it is a low power single purpose computer that doesn't have a bunch of extra processes running and its board is designed specifically to minimize noise getting passed to the dac. Everybody who's heard it here had an eargasm. Cheers,
