Computer Audiophile - Overall Product of the Year 2016
Digital Audio Review - Knockout Award
Audio Stream - Runner Up Product of the Year 2016

The microRendu is an audiophile micro computer with Ethernet input and USB Audio output. The microRendu utilizes a proprietary printed circuit board with only the essential components. The microRendu is small and light weight. Connect the microRendu directly to your USB device via a USB cable or hard adapter eliminating the need for a USB cable. Don't let the size fool you though because it's been designed to take into consideration all that is important to USB Audio. The microRendu is easy to configure and can accept audio streams from several digital sources.

What makes the microRendu different from a typical computer music server is that it's a purpose built audiophile device. The problem with computer music servers is that they all rely on mass produced motherboards designed for general purpose computing and are built to the lowest possible price point. The microRendu solves this problem by removing the consumer grade computer peripherals and optimizing power supplies where necessary. The microRendu has been specifically built for processing USB audio perfectly. You can also combine the microRendu with an audiophile grade linear power supply to achieve the lowest possible noise floor.
