Sonnet Morpheus MKII Digital Analogue Converter

The Design Goal : Pure & Simple High End Digital to Analogue 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 analogue preamplifier 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.

The Sonnet offers digital to analogue conversion with a 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.

Theres no artificial sounding edge, no sense of a flat cutout image, basically none of digitals 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 recordings quality. 

Morpheus MK-II is born.

In the past two years, the Morpheus has become a huge success. In addition to its use as a normal dac, the Morpheus has also been widely used as a digital preamplifier.

Until now, its use was limited to a series of solid state power amplifiers. However, the MK-II version is now equipped with an additional -10dB attenuator that allows the Morpheus to be combined as a digital preamplifier with highly sensitive tube designs.

By means of jumper settings the output voltage can easily be reduced from 2V RCA and 4V XLR to respectively 0.7V RCA and 1.33Volt RMS which in practice comes down to -10dB.
