Mystique X and Mystique Y Comparison


Since over 80% of our customers exclusively use computer audio, we developed a version of our Mystique DAC optimized for USB. Nearly identical to our award-winning Mystique X in circuit, power supplies, component parts, and chassis, the Mystique Y delivers all the Mojo at half the price :^)

Because the Mystique Y has only one USB input we were able to greatly simplify the digital circuitry. No need for an input selector, demultiplexer, or S/PDIF receiver. The AD1865 R-2R DAC chip is directly fed by the USB input module.

Less is more.

The result is nothing short of breathtaking. Your music will come to life with harmonics, spatial cues, and emotional content that rivals the best of analog!

Time, tune, tone, and timbre.

The Mystique Y incorporates the same no-compromise ultra-purist non-oversampling direct-coupled R-2R circuitry as all previous Mystique DACs.

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 textures and spatial cues that bring you closer to the original musical performance.

Error prevention vs. error correction.

Three independent power supplies with Mundorf M-Lytic AG+ 4-pole capacitors feed seven Belleson SPX ultralow-noise ultrahigh-dynamic regulators, isolating each type of IC chip, discrete module, and clock. The power supplies for the analog sections are LC choke input and use custom Lundahl chokes. Not only does this eliminate bit read errors and isolate digital hash noise from the sensitive analog circuitry, it also provides the effortless instantaneous power that gives our Mystique DACs the incredible organic character they are known for.

The analog output stage is direct-coupled to provide the most linear and extended frequency response possible by eliminating output coupling capacitors and transformers which 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 amps and ultralow-noise Vishay TX2575 "Naked" resistors laser matched to 0.1% tolerance.

To optimize linearity left and right channels each have an independent fine-tune circuit that adjusts the voltage of the most significant bit (MSB) at the zero voltage crossing.

For isolation from grounding noise an advanced hybrid 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 lowers noise floor, optimizes linearity, and reveals subtlety and nuance that brings your music to life!

24-bit 192KHz USB Input.

Our Mystique Y DAC converts PCM format files up to 24-bit 192KHz via a galvanically isolated XMOS USB input module with incredibly accurate ultralow-noise Femto clocking.

The third independent power supply powers the digital circuitry completely isolating it from the analog circuitry. Two Belleson SPX ultralow -noise ultrahigh-dynamic regulators isolate the USB input from the USB output and from all other power supplies eliminating the need for USB buss power or any external USB reclocking or regeneration devices.
