In June 2020, on the basis of absorbing the essence of various audio circuits and continuous optimization and improvement, Ding Ding solemnly launched the new ES9038 PRO advanced audio decoder! The new version fully optimizes the original power supply circuit and analog output circuit according to the characteristics of the 9038 chip, and gives full play to the unique advantages of parallel Class A power supplies. It is perfectly integrated with the 9038 chip, with wider frequency response, better dynamics, and higher sound density. The overall tone is warm and transparent.
All decoders made by Ding Ding do not count the cost, and all use imported solder from the United States, which has been highly rated by senior enthusiasts, to achieve better materials and better sound at the same price!
Ding Ding is selling 9018（28）On the basis of more than 3,000 sets of 9038 decoders, the product has been continuously optimized and improved, and the blue is better than the blue, and it is now grandly launchedThe new version of 9038 PRO decoder in 2020!! Welcome to compare with similar products of the same price and higher price, good voice is heard!
Dimensions: 280mm wide X62mm high X211.5mm deep (There is a detailed big picture of the inside of the machine at the back, welcome to criticize and correct)
Ding Ding has a master''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s degree in computer engineering. He loves audio and radio very much. He has published more than 100 audio-related articles in professional media such as "Computer News", "Electronic News", and "Radio".Over the years, the unswerving pursuit is to tailor a better sound system for users.
The 2020 new version has seven new major improvements around sound quality and stability:
（one）Fully optimize and upgrade the power supply of analog and digital circuits, and increase the cost by nearly one hundred yuan, which is recognized by the fever communityParallel Class A regulated power supply with better sound quality, Although the production and debugging are complicated, it ensures better voltage regulation accuracy than high-end voltage regulator ICs. It supplies power to the analog output part of the decoder, and the analog filter electrolysis is more adopted.Japan original Nichicon 10000uf audio special electrolysis 2 pcs, GreatlyIt enhances the soundness of the sound, the roundness of the midrange and the low-frequency strength, the high-frequency is smoother, and the background is quieter.
The digital power supply of the chip adoptsSanyo''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s higher-level SEPF 3 pieces of 1000uf solid-state electrolysis are used in parallel,Digital filtering performance is extremely excellent, of course, the price is not cheap, each SEPF 16V 1000uf solid state electrolysis can buy 2 Philips 16V Axial electrolysis of 2200uf.
（two） While continuing to adopt and improve the quality of the 4-layered gold PCB, fully optimize the circuit board power supply and ground wire layout. The area of ??the 4-layered gold PCB has increased by more than 20%. The main chip is all surrounded by imported high-quality SMD solid capacitors and resistors. completelyAvoid high-frequency signal crosstalk caused by the pins of vertical solid capacitors, The input and output signal quality of the main chip is better, and the work is more stable. The design of the current high-end 9038 decoder is the same.
（three） Using better native USB isolation and optimization chips imported from the United States,Installed directly on the 4-layer Immersion Gold PCB,After the signal of the Italian digital interface or XMOS daughter card is optimized, it can be directly input to the main chip for decoding in a shorter way in I2S mode, because the signal loss caused by the second pin transfer is avoided, soIt has better sound quality and more stable performance than the adapter card method.
（Four）Better balanced output: Whether it is subjective listening or instrument testing, the sound quality greatly exceeds that of decoders using ES official or general balanced circuits, and the main test parameters are nearly 20% higher, which perfectly matches high-end power amplifiers, high-end monitor speakers, and high-end chips. The charm of the sound quality can be fully demonstrated.
（five）Exclusive support XMOS at the same time U8 daughter card and high-end Italian Amanero USB IIS digital interface（Both XMOS daughter card and Italian interface need to be purchased separately）, For buyers to choose according to their needs.
（six） Equipped with an ultra-high-sensitivity full-function remote control, which can remotely control the volume, input digital audio source selection and filter switching.
(seven） exclusiveSupport USB cable connection over 10 meters（Need special production, please contact Ding Ding in advance）.
From now on, buyers can purchase our carefully crafted built-in high-fidelity amp module. Based on the sales of more than 3,000 amps, the Ding Ding team adds high-quality amp functions to the decoder.Able to push all kinds of big food headphones,ConstructPerfect decoding amp integrated machine（As shown below）. The volume control of the headphone amplifier and the decoder is independent, which is more in line with the fever concept, and has a complete headphone protection circuit. Please contact Ding Ding for details.
Decoder is guaranteed for 1 year, free of charge within 1 year（Including freight）, Very low cost maintenance after 1 year（The buyer is required to be responsible for the freight）
The machine has 5 configurations: (110V version can be customized for overseas friends）
U208 version XMOS daughter card or Italian daughter card supporting DSD needs to be purchased separately. Bluetooth daughter card and IIS daughter card are also available for purchase. By default, Bluetooth and IIS are not available, please contact Ding Ding for details.
