Description
ES9038pro is ESS's flagship DAC audio decoder chip, is currently able to see the highest performance index DAC chip, according to the practice of Mu, the use of two ES9038pro, respectively, work in the mono MONO mode, making two DAC chip Individually deal with the left and right channel audio content and do not interfere with each other, greatly enhance the DAC's performance and auditory effects. Mono MONO mode The official indicator is the dynamic range of 140dBA, which is 3dB higher than 137dBA when working with a single two-channel channel. The official indicator is for reference only, but it is easy to see that the monaural MONO Mode, the signal output current of the DAC is twice as high as that of the two-channel mode, and the darkness of the sound background, the density of the sound, the degree of separation, the motion, the knot, etc. can be made significant Of the promotion.
 
Have enough experience enthusiasts know, DAC chip is only a machine foundation, the most critical is the external circuit design and adjustment, in order to achieve the use of ES9038pro and get the best sound replay effect, L.K.S Audio uncompromising around Circuit design, such as the use of two high-quality transformer to achieve six sets of AC power supply, a total of 13 groups of low-noise regulator circuit (a lot of key parts of the use of two-level regulator approach), the second level regulator using the industry to high performance Power supply chip to provide a sufficient current margin, the reaction of fast, ultra-low noise power.
 
At the same time, in order to deal with ES9038pro unique MONO mode of large current output (more than 100mA of signal current), specially designed IV conversion circuit, this part of the circuit for the pure sub-design, the substrate is the current low noise indicators Audio transistor, twin effect transistor, audio power tube, etc., the correction capacitor is also uncompromising use of silver mica capacitors, the purpose is to get the most accurate, natural voice to reproduce. This circuit mode is the traditional integrated op amp output (such as OPA627, AD797, LME49990, OPA1612, etc.) can not match.
 
 
L.K.S Audio in the most critical place to carry out the following design:
 
1. USB part, Mu has always adhere to the use of Italy Amanero's USB program, which is the industry's leading USB playback program, recognized that the program sound better than the popular xmos, and L.K.S Audio in the Italian original on the basis of improvement, based Board usb module will use six groups of ultra-low noise LDO for sub-power supply (and the original is two LDO). In addition, in the usb upgrade version, Mu sound using two Crystek ultra-low noise clock to upgrade, and provides a decoder power transformer self-powered ultra-low noise power supply module to usb module power supply, sound enhancement effect , Very suitable for the computer as a player to use the enthusiasts. And thus one can save the cost of purchasing an external digital player.
 
2. The key master clock position, the same uncompromising, uses the Crystek CCHD-575 femtosecond clock to provide a very low jitter (82fS @ 100MHz) clock supply for the ES9038pro. Experienced burning friends know that digital audio recovery, the clock is the soul of the system, the importance of the clock can be seen. And in order to pure the clock signal, L.K.S Audio from the source - power grab, regardless of the cost of using a separate set of AC power, after two ultra-low noise regulator after the supply of this clock alone, greatly enhance the sound The stability of the background, the stability of the sound imaging.
 
3. L.K.S Audio for the left and right channels were working on the two ES9038pro DAC chip design of the independent power supply, making the left and right channel power crosstalk as low as possible to a very low state, which is brought about by the excellent sound separation Degree, very accurate sound imaging stability.
 
4. L.K.S Audio three years ago to proceed with the development of discrete circuits used to replace the traditional op amp chip, because the traditional op amp chip is subject to the chip size and SOC integrated circuit of some innate factors, the composition of the internal circuit of the monomer parts Performance is very limited, can withstand the heat power is very low, basically all of the integrated operational amplifier chip quiescent current is in a very low state (less than 10mA), even if the enthusiast of the senior opa627 gold seal version is the case, Processing ES9018 / 28/38 more and more audio output current (ES9018 / 28 in the mono mode output current is about 30mA or more, while the ES9038 is more than 100mA), so the overall quality of performance can not meet the demanding needs of enthusiasts The The output of the sub-output circuit, the use of twin JFET field effect transistor input, the last pole 3A power tube output, you can easily meet the ES9038pro high current output processing, and after three years of accumulated over 100 circuit parameters tuning, sound Performance is extremely natural, Chiang Kai-shek, high and low frequency of the ductility is excellent.
 
5. With a high standard of analog output circuit,  In order to meet the best performance of this circuit, in particular the design of the same high-grade A (A) power circuit, constant current source SHUNT circuit mode design, ON Semiconductor high power Adjust the tube, and use Jensen new electrolysis, with the appropriate output capacitor and decoupling capacitor, natural sound, transparent, very balanced and very musical appeal.
 
6. High-grade system inside, the impact of each little detail can not be ignored, using Furukawa FI03 gold-plated power outlet, Cardas rhodium-plated RCA audio output, Neutirk balanced output, etc., these components for high-calorie players That is the most familiar. It is precisely the focus of these key parts in order to create a good sound system.  for the customer standard Swiss Schute frozen version of the fuse, the sound performance of fine, moist, quiet and good, more obvious can be compared to the general fuse is rough, grainy.

I bought a USB upgrade version from Hong Kong. However, I found that my unit occationally has something like pink noise when decoding DSD using USB. This only occur when decoding DSD but does not happen when playing PCM. I have tried notebook and android phone. Both have same problem. I also move the unit to other place in case it is caused by magnetic filed but the problem still there. Any idea?

Can You tell me if the I2S input is compatible with PS Audio I2S connections? I just purchased a PS Audio Perfect Wave Transport and would like to use the I2S output from the transport into the I2S input of the LKS MH-DA004. I emailed tech support at PS Audio concerning this and this is the answer: "Our I2S output is an HDMI input that uses a custom pinout. We have made this pinout widely available, and some folks have started implementing it." Can you confirm if LKS is one that does implement the custom PS Audio pinout? Thanks
