HQ-FLAGSHIP – D/A CONVERTER -THIS IS AN UPGRADE OF THE HQ9038 TUBE DAC
- Through the years, Hq-Audio has built a renowned expertise in the digital audio domain thanks to its HQ D/A converter technology. The Hq9038 Tube DAC History includes the latest HQ9038 D/A circuitry that was originally developed for the HQ-FLAGSHIP DAC which, along with its new aesthetic, makes it the most prestigious and technologically advanced Hq-Audio converter.
- The HQ-FLAGSHIP DAC case is built of aluminum that gives it its Hq-Audio signature style but its front panel has a new look with carved inclined planes that throw the logo into relief.
- The HQ circuit is a stepped D/A with an extended dynamic range of >130dB, and a perfect time alignment correction. The sonic effect is a much deeper silence, with greatly improved micro-dynamics and a spectacular transparency.
- This result is also due to the integrated power supply feeding the Hq circuits. It is inspired from the newly designed power supply used with the Dac-End, HQ REFERENCE DAC ES9018S and guarantees a perfectly pure power is delivered to the unit.
- Dedicated to ultra high end systems the HQ-FLAGSHIP is the reference 2-channel DA converter that all serious audiophiles or customers in search of the most pristine sound want in their listening room. This is an upgrade of the HQ9038 Tube DAC.
- DAC ES 9038PRO with 04 inputs, 02 USB outputs.
- All components are very expensive and famous.
- Brings impressive and lovely sound
- Play all audio formats up to DSD 512.
- Music server plays better music than the computer.
- Pure tube output
- Designed in Italy, tested in Denmark, produced: Hq-audio.
- Use DAC without Preamli.

The main characteristics of the ES9038 are the patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator.
This is the first DAC chip that does not use the master clock on I2S bus and it automatically resample the input signal at the highest resolution available 32bit 384KHz.
This module if connected to the DAC controller module is configured to select 4 different inputs:
- I2S/DSD to use with USB OEM Combo 384 (Amanero)
- Coax Spdif RCA
- AES/EBU professional transport on XLR
- Optical Toslink.
The DAC input configuration is remapped by the micontroller on DAC controller module setting the internal registers for stereo mode.Here the schematic of the final configuration after DAC remap with one I2S/DSD input and 3 spdif input.
Using the controller module is also possible use the internal high performance volume of ES9038 with characteristics better than hi-end analog types (see article).
The DAC module use a dedicated power supply for any section of the ES9038 and it need only a transformer with only 2 secondaries.
This is a critical component, the sound performances can be compromised with a cheap oscillator.
Ultra-Low Phase Noise Crystal Oscillator, 3.3V HCMOS.
The frequency 100MHz as been choiced to support any PCM and any DSD sampling frequency.
CONTROLLER MODULE FIRMWARE
The DAC controller will be ship with the last firmware available but if you want update this in the future theprocedure is very simple.
|To program the 16F877A Microchip microcontroller I have used the PICKIT 2 USB Development Programmer/Debugger (cod. PG164120 or DV164121) with a cost about 40-50$.|
|The my C source has been compiled with HI-TECH PICC-Lite™ Compiler V9.82 for PIC10/12/16 MCUs.HI-TECH Software has provided a freeware HI-TECH PICC-Lite compiler as a tool for hobbyists and students, but the licence allows its use for commercial purposes as well. It is ideal as a teaching tool for an introduction into the ‘C’ language and embedded programing on a Microchip device.|
For this new DAC has been develop a new pure vacuum tube output stage, this is a very simple differential stage but optimized to obtain the lowest distortion and better sound.
On this folllowing schematic many values has been changed in the final release.
Follows the measurements of the DAC with this output stage at the max outptu level (0dB), the decay of the distortion is linear like a vacuum tube single ended design.
