MERGING+NADAC and MERGING+PLAYER share the exact same audio specifications and features as described below.

However MERGING+PLAYER enjoys an additional CPU that allows running RoonCore on Linux RoonOS and implements a Roon Endpoint. It connects internally through Ravenna to the MERGING+NADAC hardware and enjoys then the exact same characteristics and flexibility as an external computer running Roon.

MERGING+NADAC and MERGING+PLAYER are offered in two versions:


The 8 channels of the ESS Sabre ES9008S Reference D/A converter are merged into 2 for improved linearity, greater dynamic range and a lower noise floor.


The 8 channel version can be set at any time to operate in 8 discrete channel mode, or stereo mode to enjoy the same advantages of merging 8 into 2 channels as the stereo version .


Both versions have separate headphone outputs using the same method of combining the channels for uncompromised DSD/DXD listening on your favorite headphones.

Perfect Connectivity

Analog Outputs

  • 8/2 Balanced on 3-pin male XLR
  • 8/2 Unbalanced RCA Phono connectors
  • Separate headphone sockets with 1/4" jack and mini-jack ( when connected to a network, the headphones and main outputs may be driven by different source if required)

Digital Inputs

  • Ethernet (RAVENNA/AES67) on RJ45 connector. Accepts 44.1kHz – 384kHz PCM, DXD, DSD 64, DSD128, DSD256
  • Connects from the computer using standard ASIO on Windows and CoreAudio on Mac
  • Allows cable runs up to 100m on a single Cat5e or Cat6 cable, with possible repeaters, hubs or switches
  • Asynchronous communication. The MERGING+NADAC controls the rate at which the digital audio data is sent to the DAC, not the computer or the player
  • Ultra-precise communication clocking driven by the DAC…. Precision Time Protocol is at the heart of RAVENNA, ensuring a clock resolution of one nanosecond
  • AES/EBU on 3-pin female XLR connector (44.1kHz - 192kHz PCM)
  • SPDIF Optical on Toslink connector (44.1kHz - 96kHz PCM)
  • SPDIF Coaxial on RCA Phono (44.1kHz - 96kHz PCM)

Additional Inputs

  • Word Clock Input. BNC connector
  • MERGING+PLAYER offers two additional USB ports to connect music libraries on USB drives or memory sticks and allow for maintenance and system recovery.

Perfect Ergonomics

Front Panel Controls

  • Volume adjustment using the front panel rotary control
  • Main output and the headphone output levels may be independently adjusted
  • Two headphone sockets for connecting any headphones without adapters
  • Headphones can listen to any available inputs, or external network sources

Intuitive Menus

  • Simple and ergonomic menu selected by the front panel rotary control
  • Easy source selection between the digital inputs and the computer sources available on the network
  • Intuitive menu hierarchy
  • Multilanguage user interface

Universal remote control

  • Web based and iOS App remote control of menu functions and volume. Any web enabled smartphone, tablet or computer can control the listening level and the source selection of any MERGING+NADAC on the network. Apple iPad and iPhone can install the iOS NADAC app available on Apple App Store as well. This allows you to remotely control any MERGING+NADAC in any zones in your building with a unique remote control: your phone or tablet.
  • While also enjoying the above remote control features MERGING+PLAYER internal Roon Core can be controlled by any Roon Remote apps running on iPad and iPhone as well as Android devices, offering full volume and mute control from the Roon Remote app.
