Since the release of the AMBRE by Metrum Acoustics, the ROON enabled Digital Bridge, this first Roon Ready digital bridge product from Metrum Acoustics has been making waves in audioland. The AMBRE made its launch in April 2018 and builds upon our years of experience in digital to analog converters. The AMBRE Digital Bridge combines high quality components known by thousands of Metrum Acoustics worldwide and combines it with the user-friendly interface from Roon Labs. Recognized for its perfect clocking there hardly is another streamer product available which adds so much detail to music.

At Metrum Acoustics we are fanatic about building the best Digital to Analogue converters because of our love for making digital music sound sublime!

The AMBRE out of the box comes as a ROON certified digital end point, however because of its architecture it is also capable of running different platforms such as DietPi and PiCorePlayer. This allows for even more possibilities such as playing Qobuz or Logitech Media Server content, or even being discovered in a network using UPnP.

At Metrum Acoustics we do not believe in “taking prisoners”, hence the choice to provide our clients with an open platform. Using our AMBRE, a client could swap the SD card installed, and open up a whole new world with content from different providers, such as Qobuz. Adding web radio and play it throughout your house, office, wherever you wish to enjoy music, installing Logitech Media Server might be the solution. As for warranty we are OK with you choosing freedom, however as long as the changes apply to the software. Once the hardware is being manipulated, warranty is voided.

The AMBRE comes with I2S and other input/ouputs like AES. As I2S is not a industry standard, manufacturers do tend to use their own interpretation of the pin settings. By now we have “connected” the AMBRE with a multitude of different inputs, and sometimes the pin setting has to be changed, yet we can guarantee it does work. We are more than happy to provide the correct pin setting for most devices in the market.

Because of this dedication to perfection we can truly appreciate listening experiences like ROON.

Roon looks at your music and finds photos, bios, reviews, lyrics, and concert dates, and makes connections between artists, composers, performers, conductors, and producers.

The AMBRE Endpoint is a great addition to any audiophile setup because of its high quality components and with an array of digital inputs including Coax, Toslink, and AES/EBU, as well as I2S the Metrum Acoustics AMBRE can serve as a hub for connecting digital inputs from television, CD, or other digital sources.

  • LAN (local area network) input:  Connect an UTP cable with your local network. The Ambre is made as a Roon  end point  and cannot work as a  standalone device. The Ambre expects a working Roon music server on the same local network.
  • Coaxial Output: A 75 Ohm coaxial cable should be used to connect the Ambre to other digital audio equipment like a dac for instance. The coaxial output  has a galvanic  isolation and can handle a maximum sample rate of 192 kHz.
  • AES/EBU digital output: When using the AES /EBU digital output a special 110 Ohms XLR cable should be used to connect the Ambre to other digital audio equipment. The AES/EBU interface has a galvanic isolation and can handle a maximum sampling rate of 192 kHz.
  • Optical  output:  A standard Toslink cable can be used to connect the Ambre to other digital audio equipment. The max sampling rate of the Toslink interface is limited to 96kHz.
  • I2S output: The I2S connection is probably the best way to connect digital audio equipment  over short distances without intervention of all kind of interfaces like AES/EBU , spdif or Toslink. However still I2S is no international standard in terms of ruggedising the format or the connectors used. The I2S standard is optimized as an  interconnection between Metrum Acoustics products but will work in most cases in conjunction with other gear. If your Metrum Acoustics product has the I2S option installed you can use a simple UTP cable to connect both devices.

    I have had the Ambre for quite some time, and even think of the first, he or should I say it preceded devices of the more expensive type, although with more options, but which I never used. Recently I started using a fiber system on the Metrum .. unbelievable what the Ambre performs and connected to aes / eub on an Adagio makes it really complete, it seems even better with I2s but I don’t need it because of it already top sound, pleasant sound and not digitally exhausting.

    I finally took the step to connect my Metrum Acoustics Jade to the Metrum Ambre Streamer. But in this step I also have replaced the USB connector in the Jade with the I2S module. Something you can easily do yourself.

    Of course it’s all about the experience of Hi-Fi audio, and because I can still use my old streamer on the SPdif connection of my Jade, I have a nice comparison. Because no other components in the set have been modified outside of the Ambre, it is surprising that a streaming component in my set can make such a difference in sound image. The I2S option must have an input here.

    The biggest adjustment to the sound image is in the bass. Bass is more compact, detailed and in better placed. Second point, the sound stage is more open, and gives better room in particular to the voices and percussion. Thirdly, everything sounds more ‘musical, somewhat easier and layed back.

    This adjustment on the advice of Metrum Acoustics itself pleased me very much. I am personally advided and supervised by one of their engineers.

    Thank you Metrum.

    I am running Roon on a dedicated Server (Intel NUC) and In the Benchmark DAC3 I have found my perfect DAC…

    Since I am definitively no fan of a direct USB and/or SPDIF between ROON and DAC I was in need for a Bridge who could access my network via fixed ethernet on the on side and AES/EBU on the other side.

    The Metrum Acoustics AMBRE does exactly that.. Plugged it in between and forget it. Sound quality is what I am thiving for… Since then I’ve compared this setup with various other options in various (hi-End) systems.

    This combo always does it for me, hands down… Kudo’s for the Metrum Acoustics AMBRE…!!!

    The Ambre is an excellent interface between my IntelNUC and the Adagio. Roon is running very stable and the I2S interface to the Adagio is the best
    connectivity I have tested so far. The sound quality is uncredibale high for a fair pricing.

    I bought the Ambre just before the Pavane arrived this month in anticipation of using the i2s module. Initially I setup the Ambre connected to my Menuet DAC via AES. Right out of the box the Ambre has rivaled every other Roon end point streamer I have owned. I have since sold two from other manufactures. Roon locates the Anbre right away, and interestingly enough changing tracks from one artist to another is significantly faster with the Ambre versus Auralic or Bryston. It’s as if the Roon end point and the Roon Core are a match made in heaven. No drop outs, just simply works.And now with the Pavane over i2s, I can still connect my Menuet over AES while I am breaking in the Pavane. Couldn’t be happier.
