Sonnet Digital Audio Morpheus Mk II DAC
Best R2R DAC for audiophiles seeking a natural, preamp-free listening experience.
The Sonnet Morpheus Mk II DAC delivers a natural and inviting musical presentation, preserving nuance without artificial harshness. It allows deep insight into recordings and their quality, offering a fast transient attack and accurate image placement. This DAC provides remarkable resolution, a room-filling soundstage, and tight, tuneful bass. Its balanced, non-oversampling design features two SDA-2 DAC modules per channel for exceptional linearity and a realistic 24-bit dynamic range. With its integrated volume control, it can serve as a pure digital source, eliminating the need for an analog preamp. The Sonnet Morpheus is a non-oversampling R2R D/A converter designed by Cees Ruijtenberg. It utilizes four Sonnet developed SDA-2 R2R modules, each containing two 20-bit R2R ladders and an FPGA, to achieve full 24-bit decoding. The Morpheus offers digital inputs via optical, coaxial, AES/EBU, and USB, with optional MQA module support. It features analog outputs over RCA and XLR and a unique volume control that adjusts voltage directly from the DA chips. This DAC is praised for its relaxed, nuanced, and organic presentation, offering a lifelike and rewarding listening experience.

Know before you buy
Yes, the Morpheus Mk II features an integrated volume control that adjusts voltage directly from the DAC chips. This allows you to use it as a digital preamp, eliminating the need for a separate analog preamplifier in your signal chain.
Unlike common delta-sigma DACs, the Morpheus uses a non-oversampling R2R ladder architecture. This design is prized for its organic, lifelike presentation and ability to preserve the natural nuance and transients of a recording without the artificial harshness sometimes found in digital audio.
No, the Morpheus Mk II does not support DSD. It is specifically engineered as a high-performance 24-bit PCM DAC utilizing proprietary SDA-2 R2R modules.
MQA support is not standard; it is available as an optional, user-installable module. You should check if your specific unit includes this module if MQA decoding is a requirement for your digital library.
The RJ45 input is a proprietary I2S connection designed to provide a high-quality, low-jitter digital link specifically for the Sonnet Hermes streamer. It is not compatible with standard Ethernet network audio protocols.
Yes, the Morpheus Mk II is designed with modularity in mind. The SDA-2 R2R modules can be upgraded or serviced by the user, providing a degree of future-proofing for your investment.
