What is the Mystique Z?

Built around vintage Burr-Brown PCM58P DAC chips.

Ethereal harmonics. Luscious midrange. Tuneful bass. Of all the vintage R-2R DAC chips we've auditioned the PCM58P portrays the most natural timbres and most nuanced emotional content.

Combined with power supply upgrades, a re-engineered digital input board, and more advanced anti-resonance and grounding, the Mystique Z retains the organic character that Mojo Audio has become known for with an added sense of flesh, breath, depth, and dimension.

Raising the Bar on R-2R!

What's new?

• Vintage Burr-Brown PCM58P R-2R ladder DAC chips.
• Active buffered S/PDIF coaxial and TOSLINK optical digital inputs.
• Three-stage steep-slope anti-aliasing low-pass digital output filter circuit.
• Luscious sounding organic polymer main and paper-in-oil bypass capacitors.
• Four-bit trim adjustments to optimize linearity and minimize distortion.
• More compact design re-engineered to minimize signal path.
• More advanced anti-resonant and grounding typologies.

Time, tune, tone, and timbre.

Our Mystique Z incorporates the same no-compromise ultra-purist non-oversampling direct-coupled R-2R typologies that Mojo Audio is famous for.

With no pre-digital filtering, digital noise shaping, upsampling, oversampling, or error-correcting algorithms, our digital signal path is the purest possible.

The result is the most natural time and tune you can get from a digital source. Effortless micro-dynamics and incredible micro-details preserve the tone, timbre, texture, and spatial cues that bring you closer to the original musical performance.

Error prevention vs. error correction.

Three independent power supplies isolate digital and analog circuitry to eliminate bit read errors. Each power supply incorporates a bank of anti-resonant organic polymer capacitors with mil-spec paper-in-oil bypass capacitors. Those in turn feed nine Belleson SPX ultralow-noise ultrahigh-dynamic regulators to isolate each type of IC chip, discrete module, and clock. The analog power supplies are LC choke input and offer three performance levels of Lundahl balanced C-core chokes: ferrous core, amorphous core, and nano crystal core.

The analog output stage is direct-coupled to provide the most linear and extended frequency response possible by eliminating output coupling capacitors or transformers that can color the sound, narrow the bandwidth, and cause phase and time distortion. For ultimate transparency the direct-coupled output stage incorporates Staccato class A discrete op amp modules and ultralow-noise Vishay TX2575 "Nude" resistors laser matched to 0.1% tolerance.

Our hardware-based demultiplexing circuit has notably lower noise than any processor or FPGA demultiplexer. It assures 100% phase and time coherency between channels by using a bank of six low-noise logic gates to perfectly align the bits of the left and right channel digital words to the same clock cycle.

For isolation from grounding noise an advanced hybrid star/plain grounding schema is used to isolate input, digital, and analog grounds. And a DC ground lift switch isolates signal ground from Earth, chassis, and AC grounds.

Our unique ultra-purist approach unlocks the potential of your favorite recordings.

Minimized distortion and optimized linearity.

The PCM58P is one of the most sophisticated R-2R DAC chips ever designed.

It has the option to optimize linearity and minimize harmonic distortion with four fine tune bit adjustments: MSB, 2nd bit, 3rd bit, and 4th bit.

By comparison the AD1862 DAC chips used in our Mystique v3, EVO, and X only had one fine tune linearity adjustment for MSB.

Three 24-bit 192KHz PCM digital Inputs.

Our Mystique Z converts PCM format files up to 24-bit 192KHz via galvanically isolated Femto clocked USB, S/PDIF coaxial, or TOSLINK optical.

The third of our independent power supplies powers our digital input board. Five Belleson SPX ultralow-noise ultrahigh-dynamic regulators isolate each input stage and eliminate the need for USB buss power. Ultralow-noise femto clocking and galvanic isolation are use to eliminate the need for external USB reclocking or regeneration devices.

Another unique feature in our Mystique Z is a USB lift switch to 100% eliminate noisy clocking inside the chassis lowering noise floor even further to optimize the performance of the S/PDIF coaxial and TOSLINK optical inputs.
