After half a year of testing and adjustment, by March 2017, Musheng finally completed the new ES9038pro decoder-MH-DA004, the new decoder is positioned as the flagship of the family. The new flagship machine is based on Musheng’s accumulated experience in the past ten years, and many high-end components are used, such as the German Mundorf Mondolfo MCAP gold electrolytic capacitor, Crystek femtosecond clock, Furukawa power socket, Cardas rhodium-plated audio socket, AudioNote gold-silver alloy solder and Mundorf Supreme’s flagship gold-silver solder were used in key positions, laying a very good sound foundation for this new decoder. At the same time, after repeated auditions and adjustments by many enthusiasts, the sound is very natural, fax, and on-site. Excellent sense, rich details, extremely high clarity and transparency, abundant sound density, huge dynamics, and extreme extensibility of high and low frequencies. The previous ES9018/9028’s lack of sound quality has been changed, and the comprehensiveness of the sound quality has reached a new height.
MH-DA004 provides two configuration versions:
The first is the standard version, the price is 9399 yuan, the internal use is the standard Italian Amanero USB module of Musheng, the module uses ordinary active crystal, without independent power supply, when using it, connect the decoder and the computer through the USB cable , The USB module supplies power from the USB port of the computer.
The second is the USB upgrade version, the price is 9999 yuan, the upgrade version improves the two most critical positions affecting the sound-power and clock, Musheng uses two expensive Crystek CCHD-957An active clock with ultra-low time base jitter, and an ultra-low-noise linear power module is designed for USB work. This power module is directly powered by the AC transformer of the decoder, which can greatly optimize the quality of USB power supply. The upgraded version of the sound has the same characteristics as the high-end CDT, the sound field is open, the sound is fresh and moist, full, transparent, the two ends are excellent, the sound density is excellent, the sound is delicate and delicate, balanced and natural. The unupgraded ones are relatively flat, the high frequencies are slightly rough and protruding, and the texture is insufficient, and the low frequencies are masculine but lacking in layering.
For friends who often use USB to connect to a computer, it is recommended that you purchase the USB upgrade version.

The difference between the two versions is only in the USB receiving part, the other parts are completely the same, and the USB part will not affect the performance of other DAC interfaces.
■ Product description———————————— ————————————& mdash;————————
ES9038pro is the flagship DAC audio decoder chip of ESS, and it is also the DAC chip with the highest performance index that can be seen at present. According to Musheng’s practice, two ES9038pros are used, working in mono MONO mode, making two DAC chips Separately process the audio content of the left and right channels without interfering with each other, which greatly improves the performance and auditory effect of the DAC. The official indicator of mono MONO mode is 140dBA dynamic range, which is higher than 137dBA when working with a single two-channelIncreased by 3dB. The official indicator is only for reference, but it is easier to see the fact that in the mono MONO mode, the signal output current of the DAC is twice as high as that of the two-channel mode, and because the left and right channels can be powered separately, As a result, the darkness of the sound background, the density, separation, dynamics, and imaging of the sound can be significantly improved.
Enthusiasts with sufficient experience know that the DAC chip is just the basis of a machine. The most important thing is the design and adjustment of the peripheral circuit. In order to achieve the best sound reproduction effect using ES9038pro, Musheng will not compromise. Circuit design, such as using two high-quality transformers to achieve 6 sets of AC power supply, a total of 13 sets of low-noise voltage stabilized circuits（Many key parts use two-stage voltage stabilization）, The second-stage voltage regulator uses the current industry’s high-performance power chip to provide a response with sufficient current marginSwift, Ultra-low noise power supply.
At the same time, in order to deal with the super current output of ES9038pro''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s unique MONO mode（Signal current exceeding 100mA）, Specially designed IV conversion circuit, this part of the circuit is a pure discrete design, the base materials used are audio transistors, twin FETs, audio mid-power tubes, etc., which have very low noise indicators, and the correction capacitors are also uncompromising. The purpose of using silver mica capacitors is to obtain the most accurate and natural sound reproduction. This circuit mode is a traditional integrated op amp output（Such as OPA627, AD797, LME49990, OPA1612, etc.）incomparable.
Musheng carried out the following designs in the most critical places:
1. For the USB part, Musheng has always insisted on using the Italian Amanero''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s USB solution. This is the industry-leading USB playback solution. It is recognized that this program has better sound than the popular xmos, and Musheng has improved on the basis of the original Italian version. The board''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s usb module uses six sets of ultra-low noise LDOs for partial power supply（The original version is two LDOs）. In addition, in the USB upgrade version, Musheng uses two Crystek ultra-low noise clocks to upgrade, and provides a self-powered ultra-low noise regulated power supply module for the decoder power transformer to power the USB module, which has a significant sound improvement effect. , Very suitable for enthusiasts who use a computer as a player. And so one can save the cost of purchasing an external digital player.
2. The key master clock position, Musheng is equally uncompromising, using Crystek CCHD-575 femtosecond clock to provide extremely low jitter rate for ES9038pro（82fS@100MHz）Clock supply. Experienced fans know that when digital audio is restored, the clock is the soul of the system, and the importance of the clock can be seen from this. And for the purity of the clock signal, Musheng started from the source, the power source, and used an independent set of AC power sources regardless of cost. After passing through a two-stage ultra-low noise regulator, the clock was separately supplied to this clock, which greatly improved the sound. The quietness of the background and the stability of sound imaging.
3. Musheng has designed independent power supplies for the two ES9038pro DAC chips that work separately for the left and right channels, so that the power crosstalk of the left and right channels is reduced to an extremely low state as much as possible, resulting in excellent sound separation Degree, extremely accurate sound imaging stability.
4. Musheng started to develop discrete circuits to replace traditional op amp chips three years ago, because traditional op amp chips are restricted by the chip size and some innate factors of SOC integrated circuits.The performance of the individual parts that make up the internal circuit is very limited,The thermal power consumption is extremely low, and the quiescent current of basically all integrated operational amplifier chips is extremely low.（Less than 10mA）, Even the advanced opa627 gold version in the eyes of enthusiasts is the same, not enough to handle the increasing audio output current of ES9018/28/38（The output current of ES9018/28 in mono mode is about 30mA, while ES9038 exceeds 100mA）, So the overall quality performance can not meet the demanding needs of enthusiasts. The discrete output circuit developed by Musheng adopts twin JFET field effect tube input and 3A middle power tube output at the end, which can easily meet the high current output processing of ES9038pro. After three years of accumulated more than 100 circuit parameter adjustments, the sound The performance is extremely natural, neutral, and high and low frequency ductility is excellent.
5. It has a high-standard analog output circuit. In order to cooperate with this circuit to achieve the best effect, Musheng specially designed the same high-endCategory A（Class A）Power circuit, constant current source SHUNT circuit mode design, ON Semiconductor high-power adjustment tube, and use Mundorf electrolysis, with appropriate output capacitors and decoupling capacitors, the sound is natural, transparent, very balanced and very musically appealing .
6. In high-end systems, every tiny detail that affects the sound cannot be ignored. Musheng uses Furukawa FI03 gold-plated power socket, Cardas rhodium-plated RCA audio output socket, Neutirk balanced output socket, etc. These parts are for high fever players. It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s the most familiar. It is precisely these key parts that can create a good sound system. Musheng provides customers with standard fuse of Swiss Shute refrigeration version. The sound is delicate, warm and quiet. It is obvious that it can be compared with ordinary fuses that have roughness and graininess.
All ports of MH-DA004 DAC support DSD input（Coaxial, optical, BNC, AES/EBU are DoP input, USB, I2S, etc. support DoP, DSD native source code input）
