MERGING+NADAC   Network Attached Digital to Analogue Converter


MERGING+NADAC was born out of the repeated request from Merging’s mastering and recording engineer customers to provide a DAC for the audiophile market. This would be for their own customers, the music lovers, the high-resolution lovers, the purity lovers, a DAC able to reproduce the same experience, the same transparency they, as engineers, enjoyed in their studio when working on their Masters.

The universally acclaimed sound quality, transparency and precision of the Horus and Hapi professional converters was something these engineers were dying to offer to the people who were purchasing their music, their chef d’oeuvre.

We carefully listened and designed MERGING+NADAC based on the Horus and Hapi architecture and principle, but with a lot of improvements expected by the audiophile market, like channel summing, dedicated headphone DA, unique ergonomics and of course a superb aluminum chassis.

Not only did we deliver state of the art music listening in an audiophile environment, but also introduced some radical design enhancements to MERGING+NADAC, like tablet and smartphone remote control as well as some of the recipes which made Horus and Hapi such a great success and revolutionary in their own market. Most notably, the network audio communication through RAVENNA. You will find below some details about the benefits of this technology.

MERGING+NADAC has been immediately acclaimed and adopted worldwide and is now distributed in most territories. Please refer to our Sales section to find a distributor near you.

Many ecstatic reviews have been published confirming that MERGING+NADAC is definitely something special. Please refer to our News section to find a collection of rave reviews from many countries. Prestigious awards have also been a pleasant feature of the last year.

  • “In fact, the NADAC did wonders with this track: Podger’s instrument sounded like no mere facsimile of a violin. Instead, the sounds of the strings were so tangible that I felt I could reach out and wrap my hand around them. The highest frequencies were delicately rendered and sounded completely natural -- the antithesis of early digital. There were no hard edges, no overly crisp transients -- just beautiful sound.”
    Jeff Fritz
    SoundStage! Network

I am listening to the results here at PF Central, and am deeply impressed. This is the real deal, setting a sonic performance benchmark that other DSD DACs will have to address.”
    David Robinson
    Positive Feedback
  • “If you’re getting the sense that the NADAC was easy to listen to, you’re right.”
    Jeff Fritz
    SoundStage! Network
  • “Only a tiny number of handful of digital devices I’ve heard manage to combine all those virtues without a significant downside.”
    Alan Sircom
    HI FI+
  • “In terms of features, the NADAC is a next-generation device, replacing the USB connection that has become the standard way to connect a DAC to a computer system. Instead, the NADAC’s Ethernet port, implemented in conjunction with an industry-standard software protocol (Ravenna), delivers network capability so that the NADAC can access music from a variety of computer-derived sources throughout the user’s home. This functionality should easily become the new standard; I think it will replace USB as the de facto method for connecting computer devices to an audio system. It works great.”
    Jeff Fritz
    SoundStage! Network
  • “I was taken aback by how natural the applause, whistling and other audience sounds were reproduced. The clarity and detail was as though the NADAC was being used with an external clock – although none was actually connected.”
    Takahito Miura
    Stereo Sound
  • “The Merging NADAC has an important tale to tell audiophiles – it shows us that what the pros really work with is really good quality equipment, after all.”
    Alan Sircom
    HI FI+
  • “Nec plus ultra. I have not heard a clearer and cleaner reproduction of DSD at all levels than that offered by the NADAC.”

NETWORKING


Network Attached Digital to Analog Converter

Nice acronym, but what is it all about? The modern world has become dependent on networks and the technology has been designed to be reliable and scalable. As the network capacities have increased, the possibility of using IP networks for video and audio became an obvious choice. Clearly Gigabit Ethernet had sufficient capacity for high quality audio but it was not optimal without an additional protocol adding the required precision and management. Merging needed to move away from the PCIe technology that had served us well for many years and we looked at alternatives that could offer sufficient accuracy and reliability with high channel counts and Hi-Res Audio data rates. Other IT based point-to point connections such as USB or Firewire were either not optimum or obsolete for audio even though other manufacturers had pressed them into service. There was only one choice that made sense: RAVENNA.

RAVENNA

This open and published IP network technology had been created to meet the demands of national broadcasters and focused on essential requirements of extremely accurate clocking, high resistance to packet loss and very low latency. Initially it did not encompass high PCM sampling rates and certainly not DSD. However, it was not difficult to make changes to allow that, so Merging worked closely with the developers to make sure that sufficient channels at up to DSD256 could be handled with an accuracy that exceeded anything previously available. It remains the only logical choice for the professional and the audiophile and is now available in MERGING+NADAC. The added bonus to using an advanced networking solution is being able to send and receive control information as well as audio data. This opened up exciting possibilities in the studio and now you can enjoy these same benefits in your own home.

COMPATIBILITY

The RAVENNA protocol comes with absolutely standard drivers for any computer operating system. ASIO for Windows, CoreAudio with DoP support for MacOS. As easily installed and configured as any other driver for USB or Firewire, the MERGING+NADAC RAVENNA driver allows use of any application of your choice to playback your music files, Emotion, JRiver, Audirvana, iTunes, etc... as well as any music server or streamer able to communicate through those standard ASIO or CoreAudio drivers.

NETWORK CONFIGURATIONS


So, what is this network story about and what does it allow for ?

Better that any pontificating sentences and technical explanations, some drawings will simply illustrate the most common applications and scenarios that can be achieved with MERGING+NADAC in a networked environment !

PEER TO PEER CONNECTION TO A COMPUTER OR SERVER


Just plug a cat5e or cat6 cable between the MERGING+NADAC and any computer, music server or streamer and send audio to the MERGING+NADAC from your favorite application through the standard ASIO or CoreAudio driver. As soon as the playback application is running on the computer it will appear in the MERGING+NADAC source selection menu, exactly like any internal digital input. Select it... et voilà!

REMOTE CONTROLLING MERGING+NADAC FROM ANY SMARTPHONE OR TABLET


If you use your MERGING+NADAC with a CD transport or any other device connected to the digital inputs, just connect your MERGING+NADAC to your Wifi hotspot to access it from any web browser like Safari, Internet Explorer, Chrome, etc... You can then control the main output level and the source selection.

THE MOST USUAL CONFIGURATION


Connect your MERGING+NADAC and your computer to the same switch or Wifi router and enjoy audio playback from that computer and remote control from any smartphone or tablet.

MULTIPLE NETWORK SOURCES


Any computer, music server or streamer connected to the network can be selected as an audio source for the MERGING+NADAC. Any playback application running on any of the computers will appear in the MERGING+NADAC source selection menu, exactly like any internal digital input. A different source can even be selected for the main MERGING+NADAC output and the headphone. As above all sources can be from different application, different operating system, different computer type.

MULTI-ZONE


Multiple MERGING+NADAC can coexist on the network and can listen to the same source. Just select the same source on the front panel menu and you easily integrate a multi-zone system. Each MERGING+NADAC can however be independently remotely controlled with a different volume control.

MULTI-ZONE AND MULTIPLE SOURCES


As easy as the above examples, having multiple zones and multiple sources is as simple as plugging them on the network. Any MERGING+NADAC can listen to any source and all these devices can be accessed from a single tablet or smartphone.
