Hq9038 Tube DAC

Digital to analogue converter with Music Server

Our new ultimate DAC us chip ES9038PRO.

HQ-Audio is proud to announce the latest addition to our level ES series with the new Hq9038 Tube DAC. Under development for many years it’s quite incredible this product is available as a kit, rather it is an exceptional piece of high-end audio that can also be purchased in kit form or as factory assembled.

Hq-Audio was to build on our current DAC expertise and develop one of the finest digital to analog converters on the market today.

We leveraged our Low-Z-out power supply technology and combined that with a film capacitor architecture dedicated to delivering unparalleled performance.

The dynamics, the smoothness, the end result – a staggering experience for the modern audiophile and a chance to re-experience their entire digital collection.

The Hq9038 Tube Dac Architecture 

Looking at the heart of the digital to analog section of the DAC Hq9038 tube there are five key ingredients:

1. All new digital DAC board using 7pcs of the Ultra low noise Regulator LT3042 (<1 uV noise) to feed ultra quiet DC voltages to the digital board.

2. i/V conversion with a dedicated resistor to  transfer the analog signal from the DAC board to the Tube board.

3. Analog output stage encorporating a 12AU7 & ECC99, zero feedback  configuration with both single ended output using RCA connectors and true balanced output using XLR connectors.

4. Beautiful remote control.

5. Music server using 1.2GHz quad core CPU  in a Raspberry Pi 3 setup.  The Server runs the Linux operation system.

All the settings can easily be memolised. The Remote is the PERFECT COMPANION FOR YOUR DAC.

Real Analogue output With Tube i/v

The HQ9038-Tube DAC has an Analouge output design that surpasses all earlier designs. The DAC chips balanced output are converted to unbalanced 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.

Balanced Output & Unbalanced Output


Power supply for Pre, Phono, Loudspeakers .. Audio system is very important, it is the power supply factor and feeds the whole audio system. Not only that, power is also a key factor in determining the output audio quality. Basically, it must be clean enough so that the system does not have a lot of noise. Hq-Audio has succeeded in using and designing voltage sources for audio systems such as Pre, Phono, DAC, Amplifier …,The Hq9038-HV regulator is one of the high voltage voltage regulators designed for preamplifiers using the Tube with the following features:

Music Server in HQ-9038 Tube Dac 

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.

HQ Audio has seleceted the Raspberry Pi3 for music server, as this is the Music source that plays with an immersive listening experience that HQ Audio appreciate and admired for playing music better than a most then most of computers used as Music server.
