First class components from first class manufacturers!
We are using dual DAC 2 x ESS9038Q2M - the newest generation of SABRE Digital to Analog Converter. The new
benchmark in audio excellence. The ES9038 SABRE DAC is a high-performance 32-bit digital to analog converter and
uses ESS’s patented 32-bit Hyperstream II modulator architecture and Time Domain Jitter Eliminator. It is the first
SABRE DAC to use new Dual-DAC architecture to further enhance performance. It also delivers an unprecedented dy-
namic range of up to 129dB and total harmonic distortion plus noise of -120dB (THD+N) – a performance level that will
satisfy the most demanding audio enthusiasts.
ESS9602 - headphone amplifier and output buffer. Supports a dynamic range of up to 122dB and THD+N of -117dB
with 600ohm loads. Additionally, we implemented a unique feature that improves THD+N with 32ohm loads to -112dB in
Best Performance mode.
ESS9311 - is the industry’s first low-noise, low-dropout regulator designed specifically for high-performance audio sys-
tems. It is optimized for high resolution audio thanks to its revolutionary dual regulator architecture. This innovative ar-
chitecture contains series-voltage and shunt-voltage elements, eliminating the need for output decoupling capacitors –
an industry first in audio system design. The ESS9311 provides the extremely low-noise outputs that are necessary for
driving the reference inputs of audio converters and offers significant value-add for audio system designers.
Organic polymer capacitors are used in critical positions like the analogue power supply. These capacitors are very low
thermal drift which result in consistent playback performance. Precision Thin Film MELF resistors - such resistors has
very low voltage coeficient. It results in perfect sounds without impurities. 16-core XMOS USB chip for asynchronous
USB data transfer and MQA unfolding. Gold plated four layer PCB with extra shielding for achieving optimal audio per-
formance. Full colour OLED display for indication of volume level, selected input, sample rate and type of input digital
signal.
Synchronization of all oscillators
This extremely important feature is almost always overseen. Imagine an orchestra without a drummer or a conductor.
Every musician plays in his own rhythm and tempo. The result is chaos which nobody can listen to. The same applies to
oscillators in a DAC. There are a lot of oscillators with different frequencies and they start to talk chaotically - what could
the result be? The complete opposite happens when all the oscillators are perfectly synchronized and work like an
orchestra with the perfect conductor. This results in low jitter, minimizing of interference and it is very important for good
sound.
