The Sonore opticalRendu project is an extension of the microRendu and ultraRendu projects that came before it. The design is inspired by audiophile gear and meant to bring grace and simplicity to a microcomputer. The original microRendu was very small and intended to be hidden out of sight behind your other gear. The opticalRendu can be powered by your favorite power supply. The opticalRendu has optical Ethernet input and USB-Audio output with all the connectors located on the rear of the unit for easy cable routing. The opticalRendu utilizes a new proprietary printed circuit board with only the essential components and many updates to match its optical designation. The best way to connect the opticalRendu to a USB device is via your favorite USB cable. The opticalRendu is easy to configure, accepts streams from various sources, and includes our latest version of our operating system Sonicorbiter v2.8.

    • Mode #1 – SqueezeLite Output – This output works with any Logitech Media Server and compatible controllers. This output supports true gapless playback of PCM, DSD/DoP, and native DSD.
    • Mode #2 – ShairPort Output – This is an AirPlay emulator that utilizes streams sent to it from a compatible source. This output supports true gapless playback of PCM.
    • Mode #3 – MPD/DLNA Output:
      Mode #3a – DLNA Output – This output utilizes streams from UPnP/DLNA servers and controllers. This output can be configured as an OpenHome renderer. This output supports true gapless playback of PCM, DSD/DoP, and native DSD.
      Mode #3b – MPD Output – This output is intended to work with an SMB mount. This output supports true gapless playback of PCM, DSD/DoP, and native DSD.
      Mode #3c – Songcast Output – This output accepts streams from your computer running Linn Songcast. The application is in Beta form.
    • Mode #4 – HQ Player NAA Output – This output utilizes streams from Signalyst’s HQ Player running on your computer. Digital signal processing is performed by HQ Player and then asynchronously streamed to the Network Audio Adapter (NAA) output. This output supports true gapless playback of PCM, DSD/DoP, and native DSD.

1 review for Sonore opticalRendu

  1. TC

    After three good years feeding my DAC with a Sonore microRendu (powered by an UpTone LPS-1), which had taken my system’s sound quality into a new league, and which was further improved by the addition an UpTone Iso Regen, I have now added a combined set of upgrades that is the most dramatic improvement I’ve ever experienced:

    Adding 1) an UpTone EtherRegen ethernet switch feeding, via optical fiber, 2) a Sonore opticalRendu powered by a Farad Super3, replacing the microRendu (I’ve kept the Iso Regen in the chain).

    Joel here at Metawave was fantastic to work with — prompt, very communicative, and helpful before, during, and after the sale, volunteering a variety of useful information and working generously to get me the package of opticalRendu, Super3, and fiber and power cables and other options that would deliver the best results at a reasonable price, and in a short time frame.

    Now, after a few weeks of burn-in, the combination of the EtherRegen and the opticalRendu powered by the Super3, plus Iso Regen, has achieved, in my system at least, a stunning synergy: whole new levels of intimacy and presence, percussive detail and impact combined with supreme gentleness and removal of harshness, and almost awe-inspiring expansion of the width and depth of the soundstage into the kind of holographic immersion that I’d heard others talk about but hadn’t fully experienced before.

    I have no relationship with Joel or Meta Wave other than as a satisfied customer — I just want to thank him for helping me to take these combined steps, which can seem daunting (I was hesitating myself), but which turned out to be more worthwhile than I’d imagined. It’s a cliche but I feel it’s true: now it’s like hearing all my music again for the first time.
