Digital circuits:
The DAC unit is based on the ES9038 Sabre32 reference
DAC chip from ESS Technologies. It has a patented 32-bit
hyberstream DAC architecture and Time Domain Jitter
elimiminator. The Dac chip has build in filters for both PCM
and DSD and these filters can be adjusted by the user.
The Dac board is supplied from 9 low noise regulators
where 7 pcs are discrete extreme low noise LT3042
regulators are used for the most critical circuits.
The analog output is true unbalanced and full
banlanced.
Real Analogue output With Tube i/v. Balanced Output &
Unbalanced Output.
The Analog circuits are designed as a input stage is a
differential amplifier with 2 x 12 AU7 and 2 X 6DJ8 output.
The HQ9038-Tube DAC has an Analouge output design
that surpasses all earlier designs. The DAC chips balanced
output current are converted to a voltage using the HQ
unique technology. That gives a great experiences and
creates unbelievably stunning soundstage.
In particular, the output of the DAC has an impedance of
less than 100 Ohm and 3VRMS. Wich makes it ideal for
connecting the ES9038PRO to the power amplifier without
the need for a pre-amplifier, giving the strongest clarity in
the sound. In addition, the high-voltage supply for the
Tubes in the analouge output is optimized using Mosfets
vith very low internal resistance and a noise level of 1 uV.
The high- voltage supply are equipped with high end
components and includes several non-polarized MKP
capacitors that provide crystal clear sound, increased
dynamic and create deep and wide sound stage.

Music server
DAC integrates a Rasberry Pi3 to be the dedicated Music
Server. It Take advantage of the endless digital music
sources, especially the DSD64 format are very close to the
sound of the SA-CD. The time for using bundles of
expensive CDs and SA-CDs is over. This Music Server will
give you choose High resolution audio files. Actually, the
DAC plays all formats of digital music file.
