Precision materials


1. ES9028pro parallel two-channel decoder, use two ES9028pro chips, ES9028pro work separately in the left mono and mono mono mode, the benefits are doubled than single-chip output current, the sound density is stronger, the details More, better sense of music.

2. Multi-channel independent power supply, left and right channel power supply, the power supply of each part of their duties, effectively improve the function of different power block interference. The analog output part adopts specially designed fully separated parallel power supply (200mAX2 fully separated Class A parallel power supply circuit, constant current source + mirror amplifier circuit + Wollman circuit extension frequency), which contributes greatly to the sound, the overall tri-band sound balance, low frequency Dive depth, IF thickness, high-frequency delicate and texture than ordinary linear power supply has greatly improved.

3. Built-in specially designed Italian Amanero USB module, the original license license to support the SACD replay, which is currently on the network high-definition music playback is a very powerful weapon. USB module adds a separate chip, you can cut off the computer after the insertion of USB to the overall SNR of decoding.

4. Support USB, I2S / DSD single-ended signal (RJ45), I2S / DSD balanced signal (HDMI), coaxial, BNC, AES / EBU balance.

5. Analog audio output includes standard RCA single-ended output and XLR balanced output

6. Display using VFD display, the display is exceptional.

7. The use of physical buttons easy to operate.

8. Support 0 dB ~ -127dB digital volume adjustment, 0.5dB level, very fine adjustment. But also has a remote control a key to skip the volume adjustment function.

9. Support a variety of digital filter mode settings (see the user manual). Can be arbitrarily selected, the attenuation characteristics of digital filters are different the different filter mode

10. Support decoding internal digital phase-locked loop bandwidth settings (see the user manual).

11. Support Deemphasis to turn on or off.

12. The display has 4 levels of brightness adjustable. Adjust by remote control.

13. Remote start, standby function.

14. Most settings have a memory function, the shutdown will automatically save the settings and the next start with the last shutdown when the state.

15. Dynamic range> 123dB

16. Distortion <0.0002%

17. Stereo resolution> 112dB

18. RCA unbalanced port output amplitude 2Vrms, XLR balanced port output amplitude 5Vrms.

Machine dimensions 430 * 320 * 90mm

20. The net weight is 7.0kg


This machine is also very carefully in the selection of the key parts.

1. AC power input socket use Furukawa FI-03 with a gold-plated power socket, Furukawa copper power socket can enhance the sound of the thickness and sophistication.

2. Use 2 specially designed high-quality audio with oxygen-free copper 50VA toroidal transformer.

3. Transformer input AC rectifier diodes using Philips ultra-high-speed high-current diodes.

4, the primary filter large capacitors using nichicon KG top capacitor, the other capacitor using nichicon FG and panasonic top-level FM series with. the other key parts use the ultra-low ESR solid-state capacitors,to reach the effective absorption of power supply noise, that has a very significant contribution for the stability of the sound bottom .

5. Analog part use high-power audio components of ON Semiconductor A discrete power supply components.

6. Low-voltage digital, analog circuit using low-noise ON Semiconductor low-voltage regulator, and each functional components have a separate regulator supply.

7. Excellent ultra-low jitter (US Crystek 82fs) flying seconds to provide ES9028pro, you can get an excellent degree of background quietness and better cohesion of the sound.

8. The use of ultra-low contact resistance Fujitsu Takamizawa signal relay as a switch machine mute.

9. Audio output use Cardas card master rhodium-plated RCA seat, rhodium-plated RCA seat oxidation resistance and can significantly improve the wear resistance of the socket,althoughlong-term use,it will not lead to poor sound quality. At the same time, it is very helpful for enhance the cohesion of the sound .

10. remote control function, the user can more easily manipulate the decoder, power, standby and all other functions can be completed by remote control.

11. The use of expensive large-size VFD vacuum fluorescent display. Features are expensive, high quality.

12. We chose the imported nickel-plated screws, high precision, beautiful appearance, and durable anti-oxidation, to prevent the cover screws rust affect the appearance.


This machine uses the top Italian Amanero USB module, support PCM and DSD decoding in USB access mode, PCM supports 44.1K ~ 384K various rate, DSD supports DSD64, DSD128, DSD256, DSD512 (Windows).

32/64-bit XP / Vista / win7 / win8 / win10 is supported, and a proprietary driver (KS / Wasapi / WDM / ASIO) is required.

Mac OS 10.6+ and Linux UAC2 do not need to be driven.

 On the USB upgrade edition and ordinary modules of the sound is difference: upgraded version, with the same high-end CDT characteristics, sound field open, sound fresh and moist, full, transparent, excellent extension at both ends, excellent sound density, delicate sound delicate, Balanced, natural. Standard version is relatively flat, high frequency rough, protrusion, poor texture, low-frequency masculine, but the lack of layering.

For users who do not use USB to connect the computer, do not recommend that you purchase the upgrade section.

Will this DAC (with upgraded usb board) take DSD512 directly into the usb input or does 512 only work with I2S? Thank you

11/8/16 2:17 PM Asked.

Hi Ric,I2S play DSD512 is ok.USB can player DSD512,but it has a little noise when play DSD512.USB play DSD256 is ok.Thank you.

Good morning,  Is the input labeled as I2S-E an RJ45 connector? And therefor can accept an ethernet connection directly from computer/streamer? Is this connection superior to an hdmi-I2s connection? Thanks very much.

11/28/16 6:38 AM Asked.

hI jjk, L.K.S Audio MH-DA003 MK2' I2S have IIS-E PORT and HDMI port, IIS-E using RJ45 connection, but not internet port, so can't pick up the computer internet.RJ45 I2S better than HDMI I2S.Thank you.

Hello,  Reference the question below about RJ45, is the pin configuration standard for I2S? In my case I the output would be a PinkFaun I2S Bridge. Are all devices compatible for I2S over RJ45 or is it like I2S over HDMI where there are different specs? Thanks very much.

11/28/16 6:18 PM Asked.

Hi jjk,    I2S and HDMI-I2S definition will be different.  Depending on the inside of the each product specification calibration.  I2s is not standard, there is no uniform definition, each manufacturer will be different.    Thank you.
