The ROON Nucleus Plus is an always-on, powerful, digital, music server that provides multiple zones of playback, controls multiple devices, enables access to, literally, million of songs or “tracks,” and curates extensive metadata on those millions of songs or “tracks,” or albums. Further, it delivers bit-perfect data for playback, and renders a, relatively, noise-free, pristine, and natural music signal, that your off-the-shelf computer, simply, cannot match.
