A fabulous Dac designed and built
by the brilliant Benjamin Zwickel . The design deviates from the cheaper
and normal use of a Sabre chip and some other relatively inexpensive
Dac chip to the use of a R2R chip a far more costly chip .When using a
R2R chip in a NOS format , it results in a much more natural and non
fatiguing sound , yet keeps all the detail and dynamics digital
reproduction is capable of .
The v2 and v2 Plus share the same chassis, circuit board, power supply, and most parts.
The v2 Plus has some trickle down tech from our R&D on the v3:
1. Sparkos discrete op amps.
2. Galvanically isolated femto clocked XMOS USB input.
3. Larger power supply.
Performance wise the v2 Plus is about 20% better than the v2.

The next evolution of
our nonoversampling R-2R design.
Our new Mystique v2.0
digital to analog converter takes digital music to a new level of refinement
and realism. Keeping our ultra-purist nonoversampling direct-coupled R-2R
topology, we've added a discrete I/V conversion output stage, and two more
The result is the most
natural time, tune, and timbre possible from a digital source. Effortless
micro-dynamics and incredible micro-detail preserve the tones, textures, and
spatial cues that bring you closer to the original musical performance.
Error prevention vs.
A true R-2R ladder DAC
built around Analog Devices' famous AD-1865N-K R-2R DAC chip. To eliminate bit
read errors, our power supply incorporates over 237,000uf of capacitive filters
and nine Belleson ultralow-noise high-dynamic regulators that independently
isolate each stage. The analog output stage is direct-coupled to provide the
most linear and extended frequency response possible by eliminating output
coupling capacitors and transformers that narrow bandwidth and cause phase and
can't appreciate music.
With no pre- or
post-digital filtering, digital noise shaping, upsampling, oversampling, or
error-correcting algorithms, our digital signal path is the purest possible.
This is not true of many so-called non-oversampling designs that still
incorporate algorithms for noise shaping and error correction.
non-oversampling designs that use a single logic gate for demultiplexing the
left and right channel signals, our circuit assures 100% phase and time
coherency between channels by using a bank of six logic gates to perfectly
align the bits of the left and right digital words to the same clock cycle. And
to optimize linearity, the left and right channels both have an independent
circuit that adjusts the voltage of the most significant bit (MSB) at the zero
192KHz digital Input.
To minimize input
signal degradation, we use a single-source digital input module with three
dedicated ultralow-noise Belleson regulators and over 3,000uf of capacitance.
Each stage is independently powered and all stages are completely isolated from
