About the ultraRendu Plus

The Sonore ultraRendu Plus (version 1.3) from Small Green Computer / Sonore is the latest iteration of the ultraRendu line, designed as an exceptional endpoint streamer for audiophiles. It transforms a USB DAC into a network DAC with proprietary low-noise circuitry, including a redesigned USB circuit without redundant components, updated clock buffer with significantly lower phase noise, improved lower impedance and voltage regulation on the USB sub-system, and relocated clock circuit for reduced interference. It runs Sonicorbiter OS, supports multiple output modes such as RoonReady, SqueezeLite, ShairPort, MPD/DLNA, HQ Player NAA, and Spotify Connect (beta). Streams from sources like Roon, TIDAL, Qobuz (via Roon/DLNA), Logitech Media Server, and Apple AirPlay are supported with true gapless playback, POP-free DSD/PCM transitions, and compatibility with any USB audio input device. Recommended for use with a linear power supply like Small Green Computer's options for optimal performance. Includes 60-day Roon trial, 1-year warranty, lifetime technical support, and 30-day return policy. Not discontinued and actively sold.[1][2][7][8][10][13]
