Sonnet Morpheus




Pure & Simple Digital to Analog conversion with Volume control

What more can you do after launching one of the best DACs available today?

The idea of having a decent volume control to prevent a analog Pre-Amplifier could improve performance dramatically.

However, we also know that the way of introducing such device in the signal chain can also have a negative effect.

Experiments were made and as result the best sound was coming directly from our new fully balanced dac modules.

Especially in case of R2R ladder DACs it is quite easy to change the output voltage of the DAC by changing its reference voltage .

The SDA-2, a new generation DAC module was designed to get the best regulation possible.

The result of this process is an extremely high linearity, right down to -140 dB, which gives our products a realistic 24 bit dynamic range. It is musical, honors the Non-oversampling principle and simultaneously incorporating the technological progress that has been made over the years. Digital to Analog Conversion with lossless volume control.

The Sonnet range will gives you more weight, body, tonal richness, and a more natural sense of the space of the recording. Or to put it more plainly, it fleshes out your music more! This new range does a wonderful job of presenting even the most complex music in a natural and inviting manner with every last ounce of nuance in tact.

There’s no artificial sounding edge, no sense of a flat cutout image, basically none of digital’s nastier stuff. In some cases this can also come with a somewhat dark and muddy sound but that is absolutely not the case with the new Sonnet range.It allows you to hear deep into the recording and the recording’s quality.

This is somewhat of a good news/bad news proposition in that you’ll really hear what’s there.Balanced Non oversampling DAC Two SDA-2 dac modules per channel in differential mode

For MQA or I2S more information can be found here


The I2S module can be installed instead of the USB module.




A new technology is used to make the I2S data format more reliable.

Actually this format was made for internal use and not able to drive long data lines. Sonnet is using a kind of data transport based on the typical impedance of a standard UTP cable. By using this technology it is important that both transmitter and receiver is made for this quite heavy load of 100 Ohms.

As a result lengts of 30 meters between source and receiver can be used without loss and jitter.

The I2S module is dedicated for Sonnet products like for instance our upcoming Hermes. However in some cases by removing four jumpers on top of the module it will act as a high impedance receiver and therefore more flexible to match with other products.

Still Sonnet Digital Audio cannot guarantee the correct behaviour in conjunction with other systems. If you have any doubts about the correct match with our products don't hesitate to contact us. Like the standard USB option our dacs can be ordered including the I2S module .

The MQA module is available as an option and will be recognized as soon the module is installed in its socket.


The module includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. ‘MQA’ or ‘MQA Studio’ indicates that the product is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. ‘MQA Studio’ indicates it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.
