I bought these as I had plans to move over to a music server. However, I've now decided against this. I've used this to check that it works, but beyond that it hasn't had a great deal of use.

This UltraRendu comes with V2.8 of the Sonic Orbiter operating system. A PSU is not included as standard, but this comes with an Uptone Audio Ultracaps LPS1.2. The Ultracaps uses clever microprocessor technology and a banks of high quality capacitors to provide a very clean DC power input to the UltraRendu. The total retail value of both these items is £1290.00.

Price = £750 plus £10 postage for mainland UK.

I'm not sure about shipping to the EU at the moment, post-Brexit. Happy to look into it, though, if someone from the EU is keen on this.

ultraRendu​

The Sonore ultraRendu project is an extension of the microRendu project 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 ultraRendu can be powered by your favorite power supply. The ultraRendu remains as an Ethernet input and USB-Audio output, but all the connectors are 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 many 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 latest version of our operating system Sonicorbiter.

SELECTABLE OUTPUT MODES​

• 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.
