AMBRE for Roon


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

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.

What you get is a searchable, surfable magazine about your music.

And as we believe a DAC, Digital to Analogue converter is the heart of your music setup, what else can we do than to build a ROON end point which will allow you to direct your digital music through our device in order to get the most sublime sound available!




We have been working under the radar to create a high quality, as you can expect from Metrum Acoustics, ROON end point, named AMBRE.

AMBRE will be as sweet as the name sounds, a sweet little device build with high quality components in order for you to get the highest quality sound when using ROON.

AMBRE is not ready yet, currently undergoing the last tests, but to give you an idea of how she will look like, we want to share with you this sketch,



As you can see, AMBRE will have similarities to our award winning entry level DAC, the AMETHYST.


The AMBRE By Metrum Acoustics comes with all the connections an audiophile can wish for, and when hooking it up to your network it is a plug and play device.

The connections:

  • 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.

And once connected, it is setting up your ROON environment,

And from here on you can choose your destination and is the AMBRE fully operational! Enjoy the music by Making Digital Sound Sublime!
