When I found out Cees Ruijtenberg has started a new company, Sonnet Audio, I had to hear his latest creation, Morpheus. I was a Metrum dealer while Cees was still at the helm, and loved his work, and his newest creation, Morpheus, has quickly become my go-to DAC.
The Hermes is the perfect companion to the Morpheus, allowing you to stream your music through Roon and other digital sources. Here's the MFR specs:
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 UTP cable.
