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 your music. And as we
believe a 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
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
adds so much detail to music. 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 and
Volumio. 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 Sonnet Digital Audio 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. 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.
The HERMES comes with a dedicated I2S output which is based on impedance
matching. This approach makes it possible to use standard UTP cable over lengths
of 30 meters without loss or interference. Standard ouputs like AES/EBU, Coax
and Toslink are available as well. The hardware platform in HERMES enables you
to stream high res music files from network attached storage, online streaming
services through the powerful ROON platform or others, outputting bit perfect
audio direct to your DAC. The HERMES by Sonnet Digital Audio 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.
LAN (local area network) input: Connect an UTP
cable with your local network. The Hermes is made as a Roon end point and
will only work in conjunction with a digital to analog converter. The
Hermes expects a working Roon music server on the same local network.
Coaxial Output: A 75 Ohm coaxial cable should be
used to connect the Hermes to other digital audio equipment like a DAC for
instance. The coaxial output has a galvanic isolation and can handle a maximum
sample rates up to192 kHz.
AES/EBU digital output: When using the AES /EBU
digital output a special 110 Ohms XLR cable should be used to connect the
Hermes to other digital audio equipment. The AES/EBU interface has a galvanic
isolation and can handle a maximum sampling rates up to 192 kHz.
Optical output: A standard Toslink cable
can be used to connect the Hermes 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 ruggedizing the format or
the connectors used. The I2S standard is optimized as an interconnection
between Sonnet products but will work in most cases in conjunction with other
gear. If your Sonnet product has the I2S option installed you can use a simple
