(See full translation in English below)

I ordered the Ultimate version of this DAC after reading some good reviews. For around ¥2000 (under A$400) landed it seems like a well-implemented ES9038.

Built-in op-amps are four of the (Texas Instruments) LME49710 and two (Analog Devices) AD797.

(I presume the pair of AD797's are in the output/signal path and would benefit most from being upgraded? I have a couple of Burson V5i op-amps that are compatible).

Should be interesting to compare this to a few other budget DACs on my desk, including a Topping D50 (and a D30) and a basic ES90382QM circuit-board DAC with linear supply.

Five . ES9038 Ultimate Dual 30W British TALEMA Ring Bull + TCXO 0.1PPM high quality gold temperature compensation crystal oscillator + 4 imported original factory same batch LME49710NA +2 imported original AD797 op amp+ US imported USB optimized isolation chip + exclusive development of high performance balanced output circuit = 1950 yuan

In March 2018, on the basis of drawing on the essence of various audio circuits and continuously optimizing and perfecting, Ding Ding solemnly launched the new ES9038 PRO advanced audio decoder! The new version is optimized for the original power supply circuit and analog output circuit for the characteristics of the 9038 chip, giving full play to the unique advantages of the parallel class A power supply, and combining with the 9038 chip, the frequency response is wider, the dynamics are better, and the sound density is higher. The overall tone is warm and transparent.

All the decoders made by Ding Ding are cost-free. All of them use the imported solders from the United States, which are well-received by senior enthusiasts, so that the materials at the same price are better and the sound is better!

Based on more than 2,000 units of 9018 decoders, Ding Ding has continuously optimized and upgraded its products. It is blue and blue, and now it is launching the new 2038 PRO decoder in 2018! ! Welcome to compare with similar products at the same price and higher price, the sound is heard!

Dimensions: 280mm wide X62mm high X211.5mm deep (A detailed big picture of the inside of the machine, welcome to criticize and correct )

Ding Ding is a master of computer engineering. He is very passionate about audio and radio. He has published more than 100 audio articles in professional media such as Computer Newspaper, Electronic News, and Radio. For many years , he has been pursuing the pursuit of users. Customized to a better sound system.

The new 2017 version, with sound quality and stability, has seven new major improvements:

(1) Fully optimized and upgraded analog and digital circuit power supply, and increased the cost by nearly one hundred yuan. It adoptsa parallel type A stabilized power supplywithbetter sound qualityin the fever industry. Although the production debugging is complicated, it ensures better stability than the high-end voltage regulator IC. The precision of the voltage is supplied to the analog output part of the decoder. The analog filter electrolysis uses theJapanese original Nichikang 10000uf audio dedicated electrolysis 2, which greatlyenhances thesoundness ofthe sound and the roundness and low frequency of the midrange, and the high frequency is also smoother. Slip, the background is more quiet.

The digital power supply of the chip is based on Sanyo's higher-grade SEPF 1000uf solid-state electrolysis. Only 3 parallel use, digital filtering performance is extremely excellent, of course, the price is not cheap, each of the SEPF 16V 1000uf solid electrolytic can buy two Philips 16V 2200uf axial electrolysis .

(2) While continuing to adopt and improve the quality of the 4-layer immersion gold PCB, fully optimize the circuit board power supply and ground layout, the area of the 4-layer immersion gold PCB is increased by more than 20%, and all the main chip is made of imported high-quality chip solid capacitors. And the resistor completely avoids the high-frequency signal crosstalk caused by the pins of the vertical solid capacitor , and the input and output signals of the main chip are better in quality and work more stable. The design of the current high-end 9038 decoder is the same.

(3) Adopting a better imported USB isolation optimization chip from the United States, directly installed on the 4-layer immersion gold PCB, the signal of the Italian digital interface or XMOS daughter card can be directly input by I2S in a shorter way after optimization. The main chip decoding, because the signal loss caused by the 2-pin transfer is avoided, the sound quality is better than the riser card mode, and the performance is more stable.

(4) Better balance output: Whether it is subjective listening or instrument testing, the sound quality greatly exceeds the decoder using ES official or universal balanced circuit. The main test parameters are nearly 20% higher, perfectly matching high-end amplifiers and high-end monitor speakers. The sound quality of high-end chips has been fully demonstrated.

(5) Exclusive support for XMOS U8 daughter card and high-end Italian Amanero USB IIS digital interface ( XMOS daughter card and Italian interface need to be purchased separately ), which can be purchased by buyers according to their needs.

(6) Full-featured remote control with ultra-high sensitivity, which can remotely control the volume, input digital sound source selection and filter switching.

(7) Exclusive support for USB cable connection of more than 10 meters (requires special production, please contact Tintin in advance).

For now, buyers can buy our carefully crafted built-in high-fidelity headphone amplifier module, summing up the sales team Tintin amp on the basis of more than 3,000 Taiwan, to increase high-quality amp decoder function, can push all types of large good Eat headphones, build a perfect decoding amp machine ( as shown below ). The volume control of the amp and the decoder are independent, more in line with the fever concept, and have a perfect earphone protection circuit. Please contact Ding Ding for details.

The decoder is guaranteed for 1 year, free for 1 year (including shipping), and low cost of repair after 1 year (requires buyer to be responsible for shipping)

The figure below shows the actual frequency response curve of the Tintin version of the decoder tested with imported professional instruments at 24BIT 96KHZ and 24BIT 192KHZ. It is very smooth and the left and right channels maintain a high degree of consistency. The high frequency end of 45KHZ drops only 0.05db, which is an order of magnitude higher than the 0.5db of similar products. ( Similar products began to slow down from 10KHZ, weakening the detailed performance of the chip)

Ding Ding has spared no effort to improve the materials and sound quality of the products, improve the low frequency and vocal performance of the decoder, while the sound quality surpasses similar products, and has also greatly improved compared with the previous version.

The advantages of Ding Ding's new decoder in terms of sound quality and reliability.

Feature one:Ding Ding's exclusive new wiring and grounding method, at the same time, the type and value of each resistance, especially electrolysis, are repeatedly installed and audited. The instrument determines the better model, which makes the signal-to-noise ratio and dynamic range of the whole machine significantly improved. For similar products! After testing, the signal-to-noise ratio and dynamic range are improved by about 15db. Completely avoid the loss of the digital input signal that is easy to appear on the high-precision main chip! Senior enthusiasts are welcome to receive the goods with their ears and instruments.Ding Ding can also provide a simple test method that allows buyers to have an intuitive feel for the signal-to-noise ratio of their machines.

Feature 2 : Through the improvement of the power supply circuit, such as low ESR value filter electrolysis, low voltage drop high current rectifier diode, high quality ring cow, etc., the temperature of many core voltage regulator chips is reduced by nearly 20 ° C, and the whole machine generates more heat. Small and more reliable. With our decoder, you can boot continuously for more than 1 week, and the temperature rise is very low.

Feature 3: According to the feedback of senior enthusiasts and foreign agents, use higher-end imported fast high-current rectifier diodes , ultra-fast switching speed and high current up to 3A, with a forward voltage drop of less than 0.5V, performance is much better than Taiwan's passivated rectifier diodes are also much stronger than PHILIPS BYD33J! The characteristic that is reflected in the sound is that the low frequency is better and the vocals are more mellow! At the same time, it still maintains the elegant high pitch of the 9038 chip.

Feature 4: Exclusive optimization of USB power supply and signal circuit, digital signal input by XMOS daughter card, after decoding, the signal-to-noise ratio and dynamic range are obviously improved by 25~30db ( can be heard and improved, welcome to listen to PK with similar machines )!

6x burson V5= more than the price of this DAC
big fan of the bursons change the AD opamps and let us know how is goes.

there are a few discrete opamp replacement on ebay at the moment cheaper than the bursons but i’m not sure how good they are.

Thanks - yep, saw that one. This one also uses the 'Pro' chip.

(The designer's blurb is misleading because he hasn't edited out the previous info about his 9018 / 9028 DACs).

By the way, is there any way to tell whether the two AD op-amps are single or dual op-amps?

AD797 is single.

49710 are single as well

which is probably why they were matched together, must have found each other on tinder or something.

Thanks for that info. 10/10 for knowledge; 7/10 for the comedy, but don't give up...

I wouldn’t pay money for low quality components and circuit such as this, D50 is miles away better in every aspect but I’m pretty sure you’ll find out yourself

Even in China are known designers/companies worth spending money on but this is not one of them...

My preferred one would be this, it's discrete R2R and from the sounds of it can even do dsd if your into it.

You may be right; it's a risk buying something from an individual designer, although the components are not all low quality...

Must be a new brand of special type audiophile cap that we don’t know about! We should have a open mind give it some thought .....

hehe... No, that's cool. I don't mind a bit of...sage advice!

Jokes aside

great for experimenting.

Great for opamp rolling.... plenty of room to swap out components. I had a EE mini max dac plus when I 1st got onto SNA... makes you aware of how different opamps can make a difference. Also trial and error with different type PSU electrolytic with different ESR values. Be interesting if you order without those super special psu diodes and then order a set of diodes from places like E14 and swap them out! I’d personnally wouldnt use high speed diodes for full wave rectification but you never know until you try.

@was_a did you get your new DAC and what are your impressions? Thanks

Breeze Audio ES9038Pro DAC

Thanks for the question. Because of shipping delays I ended up ordering the slightly more expensive, conventional version of this DAC (marketed through eBay, AliExpress and various other online retailers). It uses 2x single op-amps and 2x dual output op-amps. This one came with a pair of AD797 and Muses 8920's.

I use a coaxial connection via a usb-coaxial converter.

The result is very good indeed. In fact, it's nearly up there with my Marantz SA11s2 spinner, and that's saying something. This extends to challenging genres such as classical music, where violins, piano etc are extremely well portrayed.

Versus my Toppings (D30 and D50) it's in the next class up, with a more refined tonality and spacious presentation. It also displays the benefits of the dual transformers - better control at frequency extremes etc.

Not that I'm criticising the Toppings - I have the D30 in another setup and I really enjoy it.
