The Sonore ultraRendu is an audiophile-grade Ethernet-to-USB network streamer designed to act as a dedicated network audio renderer for your existing USB DAC. It provides a Gigabit Ethernet RJ45 input and a USB Audio Class 2.0 output to your DAC, effectively turning it into a network-connected DAC with support for high-resolution audio formats. Built around a custom, small-form-factor PCB and enclosure, the ultraRendu uses a redesigned USB audio circuit, multiple ultra-low-noise voltage regulators, and a high-quality fixed-frequency low-jitter oscillator to minimize noise and timing errors. The operating system is stored on a microSD card, and a multicore processor with DDR3 RAM runs Sonore's Sonicorbiter OS, which is accessed via a web interface for configuration of output modes and applications. The ultraRendu supports PCM sample rates from 44.1 kHz up to 768 kHz and DSD64 through DSD512 (native and DoP), with POP-free switching between PCM and DSD. It is Roon Ready and supports multiple network streaming protocols and modes, including Roon RAAT, DLNA/OpenHome, Squeezebox (SqueezeLite), HQPlayer NAA, MPD, ShairPort (AirPlay), and Spotify Connect, depending on the installed Sonicorbiter apps. Typical supported audio file formats include FLAC, ALAC, WAV, AIFF, MP3, AAC, OGG, WMA, DSF, and DFF. All primary connectors (Ethernet, USB, power, and microSD) are located on the rear panel for clean cable management. The compact chassis measures approximately 1.181" (H) x 4.331" (W) x 4.409" (D) and weighs about 1 lb. The unit requires an external 6-9 VDC power supply at a minimum of 1 A, using a 2.1 mm x 5.5 mm center-positive connector; Sonore's own linear power supplies and other quality linear supplies are commonly recommended and sold separately. Control is via third-party apps or web interfaces on computers and mobile devices (e.g., Roon, DLNA controllers, Squeezebox controllers, or HQPlayer), with configuration and app installation handled through the Sonicorbiter OS web GUI. Retail units typically include a limited warranty from Sonore and ongoing firmware/software support via Sonicorbiter updates, though bundled trial periods for third-party services like Roon may vary by seller and region.
