## Sonnet Hermes - The Low-Jitter Digital Bridge
**Lightweight, low jitter, bit-perfect plug and play Roon endpoint. Open platform supports DietPi, PiCorePlayer, moOde, Volumio OS (up to version 3) and more.**
At Sonnet Digital Audio we are fanatic about building the best digital to analogue converters. Because of this dedication to perfection we can truly appreciate listening experiences like Roon. Roon looks at your music and finds photos, reviews, lyrics, and concert dates, and makes connections between artists, composers, performers, conductors, and producers. What you get is a searchable, surfable magazine about the music you love.
And as we believe a digital to analogue converter is the heart of your music setup, what else can we do than build a Roon end point which will allow you to direct your digital music through our streamer in order to get the most sublime sound available!
### High Quality Components
The Hermes digital bridge is using high quality components and combines it with the user-friendly interface from Roon Labs. Recognized for its perfect timing, there hardly is another streamer product available which reveals so much detail of the music.
### Open Platform Philosophy
The Hermes 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, PiCorePlayer, moOde and Volumio OS (up to version 3). This allows for even more possibilities such as playing Qobuz or Logitech Media Server content, or even being discovered in a network using UPnP.
We do not believe in "taking prisoners", hence the choice to provide our clients with an open platform. Using our Hermes, a client could swap the SD card installed, and open up a whole new world with content from different providers, such as Qobuz or Tidal. Add web radio and play it throughout your house, office, or wherever you wish to enjoy music.
As for warranty we are OK with you choosing freedom, however as long as the changes apply to the software.
### Comprehensive Digital Outputs
The Hermes comes with a dedicated I2S output which matches the impedance of all Metrum Acoustics and Sonnet Digital Audio DACs. This approach makes it possible to use a standard UTP cable over lengths of 30 meters without loss or interference. All outputs an audiophile can wish for are available:
- **AES/EBU output:** 110 Ohms XLR connection, galvanically isolated, up to 192 kHz
- **Coaxial output:** 75 Ohm RCA connection, galvanically isolated, up to 192 kHz
- **Optical output:** Standard Toslink, up to 96 kHz
- **I2S output:** Via UTP cable with RJ45 connectors, impedance matched, the most transparent connection for Sonnet DACs
The digital audio outputs can be used simultaneously.
### Galvanic Isolation
All outputs of the Hermes are galvanically isolated, ensuring that noise from the network or streaming source never contaminates your DAC's delicate circuitry.
### Plug and Play Simplicity
The hardware platform in Hermes enables you to stream high resolution music files from network attached storage, online streaming services through the powerful Roon platform or others, outputting bit perfect audio directly to your DAC. Hermes is a plug and play device.
For the ultimate Sonnet digital front end, pair the Hermes with the [**Pasithea**](/product/pasithea) or [**Morpheus MK-II**](/product/morpheus) DACs via the I2S connection for a truly reference-grade streaming system.
