## Sonnet Digital Audio Pasithea - The Pursuit of Absolute Neutrality
**Eight DAC Modules. -160dB Noise Floor. A Soundscape Without Boundaries.**
Pasithea—the personification of relaxation and meditation in Greek mythology. It is a fitting name for a DAC that transports you away from the everyday, placing you directly in the recording engineer's chair with a soundscape of startling realism and tranquility.
The Pasithea is Sonnet Digital Audio's statement above the acclaimed [Morpheus](/product/morpheus). It is the culmination of years of R2R expertise, delivering a level of performance where measurements meet musicality in perfect harmony.
### The Architecture of Silence
At the heart of the Pasithea lies a radical departure from conventional DAC design. By leveraging enormously energy-efficient electronics, Sonnet's engineers found the thermal and spatial budget to integrate **eight proprietary SDA-3 DAC modules** within the standard enclosure.
Configured in a balanced, differential arrangement (four modules per channel), this array delivers:
- **Vanishingly low distortion**, even at the most delicate signal levels.
- **A noise floor of -160 dB** - a full 5 dB improvement over the [Morpheus](/product/morpheus), revealing even more of the subtle reverberations and micro-dynamics that define a live performance.
- **Exceptionally low output impedance** (just 16 Ohms on the XLR output), allowing the Pasithea to drive any amplifier or active speaker with effortless authority, regardless of cable length or input sensitivity.
### True 24-Bit Performance, Measured and Heard
What separates a great DAC from a transcendent one is its ability to resolve the lowest-level information without error. The Pasithea's linearity plot tells the story. Down to -135 dB, proof that the DAC is extracting every ounce of data from your recordings. This is not merely a specification; it is the difference between hearing a note and experiencing the space around it.
### Flexibility Without Compromise
Designed for the most demanding systems, the Pasithea includes two versatile -10dB attenuators, one is accessible via the menu, the other via a physical switching of jumpers. This ensures seamless integration with highly sensitive tube amplifiers or high-gain active monitors, all while maintaining the Pasithea's ultra-low output impedance. When the hardware attenuator is engaged, the output impedance of the XLR outputs drop to a staggeringly low 8 ohms.
### The Listening Experience
- **Space:** Instruments are placed with laser accuracy within a vast, three-dimensional soundstage. The silence between them becomes a tangible part of the music.
- **Neutrality:** The Pasithea adds nothing and takes nothing away. It is a transparent window to the master tape, revealing the true intent of the recording engineer.
- **Life:** Life: From the softest brush of a cymbal to the full force of an orchestral crescendo, the Pasithea renders music with an organic, effortless quality that invites hours of listening. During loud crescendos all instruments stay perfectly separated, all subtle details in your music are revealed.
**Inputs:** Optical, Coaxial, AES/EBU (up to 24 bit 192kHz), I2S, USB (up to 24 bit 384kHz)
**Outputs:** RCA (2.1V RMS), XLR (4.2V RMS) - switchable -10dB attenuation
**Finish:** Black or Silver
