ultraRendu with Uptone Audio Ultracap PSU, (not included)

Above is a ultraRendu with an Uptown Audio Ultracap PS (not included)

The Sonore ultraRendu project is an extension of the microRendu project that we launched over one year ago. The design is inspired by audiophile gear and meant to bring grace and simplicity to a micro computer. The original microRendu was very small and intended to be hidden out of site behind your other gear. The ultraRendu is in a larger case and perfectly matches the Uptone Audio UltraCap LPS-1 power supply. However, the ultraRendu can still be powered by your favorite power supply because it shares the same power specification as the original. The ultraRendu remains as an Ethernet input and USB Audio output, but all the connectors are now located on the rear of the unit for easy cable routing. The ultraRendu utilizes a new proprietary printed circuit board with only the essential components and some updates to match its ultra designation. The best way to connect the ultraRendu to a USB device is via your favorite USB cable. The ultraRendu is easy to configure, accepts streams from various sources, and includes our new operating system Sonicorbiter 2.5.
