If you order now, we will send the standard version to you. Thank you! Gustard has been researching the audio field for nearly ten years, and its various audio DAC products have been widely recognized by users all over the world.

In this era of rapid development of digital technology, Gustard never dared to slack off, and has a systematic and in-depth study of audio DAC chips from many manufacturers. That is, A This discrete circuit has been very matured after many years of practical application.

This time we also made targeted adjustments to other peripheral circuits of the AK chip to improve the overall quality of the A A22 is very good in both user function and performance. The two-channel DAC circuits are completely independent and independently grounded, and do not interfere with each other to achieve optimal performance. And you can choose whether to have a built-in USB digital audio interface daughter board depending on whether you need USB input function.

Gustard DAC-X26 real shot: Rigorous design, reasonable layout, nice workmanship and solid materials The left and right channels are each using a AKM company's flagship chip AK for dual mono audio digital-to-analog conversion. The two-channel DAC circuits are completely independent and independently grounded, and do not interfere with each other to achieve optimal performance; The newly designed 8-channel hybrid discrete IV conversion circuit and independent adder circuit fully meet the requirements of the AK's large output current, ensuring high sound quality from the source; Multiple sets of independent power supply circuits ensure sufficient energy and no interference with each other; The analog LPF circuit of the A22 is a fully discrete Class A circuit that is specially designed and tuned for the AK chip.

Each discrete device only needs to consider its own performance separately, so there are fewer application limitations than using integrated op amp chips, so that the performance of individual components can be fully utilized.

Unlike transistors inside an integrated circuit that are integrated into the die and cannot be adjusted and changed, the use of discrete devices is more flexible. We can freely adjust the parameters of each stage to achieve optimal operation.

Also because of its It is more developable and relatively controllable for parts that produce distortion, giving a different variability in sound style for different audio DAC circuits.

The disadvantage of discrete devices is that their distribution parameters have a great influence, and it is difficult to design and debug. It requires certain technical experience and a long debugging process. Moreover, the consistency of the discrete circuits is relatively weak, so the materials need to be more reliable. A22's power supply circuit uses multiple independent voltage regulators and multi-stage filtering to achieve independent power supply to the left and right channels and avoid mutual interference; The digital and analog circuits each use a specially customized 50W audio dedicated toroidal transformer, which is completely independent and does not interfere with each other; The A22's built-in USB digital audio interface daughter board uses an XMOS USB audio controller XU, which supports up to PCM DSD Customers may also be subject to a restocking fee of up to 20 percent of the product cost.

It must have 4 layers or more. The power supply ripple must be uV level and the modulus must be separated. As long as it is an AK product, it must be modified at least 5 times.

That's why AK's products are so few and expensive. In order to serve the AK, everything follows the simplest design. Only physical relays are used to switch on and off.

True colors. Welcome comparison. High power consumption results in less battery life. If the full blood is output, the battery life is only a little more than 4 hours, and the fever is serious.

If you feel that the battery life is low, you can enter the DAC setting and turn off the Turbo function. In view of the player's volume and PCB area, only passive LPF can be used, which will increase the impedance of the 2. Therefore, if you want to use the 2. Zishan likes to chase new ones. This is the same idea as auxe m2 and lacquer rainbow c4, but it is higher, reaching K 32B.

People who do technology are honest, please look at the picture, the left and right channels are full of 32Bit. Get a decent DAC. Zishan Notes. When the night is quiet, when you are lazy on the weekend, and lying on the grass, Zi Shan will take it out, bring headphones, and control the world's flowers and leaves.Topping is a China-based brand which is famous worldwide for its various range of premium audio products just like Topping NX3s an amplifier which one can use portably.

It uses German Thesycon drivers. It comes with a pair of AccuSilicon MHz and It is implemented with 4 OPA opamps, 7 hi-fi capacitors, CPLD processing using 2 Accusilicon femtosecond clocks which provides a completely noise-free and jitter-free sound output.

This DAC produces a soft, smooth and lively sound quality which is why it is called Velvet Sound Verita, The sound output is natural and soft, which reproduces all the micro details in your music precisely. The sound quality is natural, smooth and crispy, you will be enjoying all your music with quite good precision, it takes inputs from the USB port. The Flagship DAC implemented in the Topping D90 is implemented with high-class components offering balanced and natural sound output, the bass is thumpy and quick, mids are natural and lush, and highs have a smooth and detailed texture.

The Topping D90 provides a wide dynamic range of dB and an amazing signal to noise ratio of about dB, which provides greater extensions at the lower and higher ends and an amazing crystal clear background, with no signs of noise.

It provides enough juice to power up any of your high demanding gears, whether it be planar headphones or speaker system. It can output through both the output ports at the same time so you can use multiple gears with it at the same time.

This volume control can be disabled to make the D90 function purely as a DAC. Total shipping lead time from our warehouse to you as follows:.

Topping is all about pure specs, numbers and measurements, the evil-scientist in me is pleased. What is there to love in a simple black box you might ask?

Another thing I like is that it has the same width as the Benchmark HPA4 and these two became best buddies for the past 2 weeks or so because of that. They look nice together and they make a great team on an office desk and if you are searching for a top-of-the-line desktop headphone rig, it just might be it.

D90 feels on the heavier side, with such a small foot-print and having 1. To me, D90 looks simplistic, has a clean look, you might even call it elegant looking. The case is beautifully crafted on a CNC machine.

As with DX7 PRO, the rubber feet are placed in 4 individual carved spaces on the aluminum case itself so you can be sure those feet will not move an inch if you are repositioning your DAC quite often as I do. The monochrome OLED screen is quite bright and offers 3 brightness levels. All in all, I have nothing to complain in terms of design and looks. D90 is a pure DAC so obviously the headphone outputs have been dropped. The up and down buttons on the right will control its preamp volume level and if you are using it as a pure DAC please leave it at 0.

Buttons are flushed and you can be sure that you will not accidentally press them. An important thing to know is that if you want to unleash the full potential of D90, you will need to use the included remote. With it you can select from 6 digital filters that are working on the hardware level, you can select 3 brightness levels, desired input and output, the volume position. If you plan on using just a single output on the back, I strongly recommend changing its output on that particular one without engaging both of them.

By doing that, D90 will operate cooler and will be less prone to noise that might come from the other interconnect cable. This is a Very special chip and I will explain you why.

If you are into computers, you probably know how important is the die-size of a CPU or GPU, a bigger size means it will have a higher performance and, in the process will consume way more electric power.

Same applies to DAC chips, as strange as it might sound, bigger DAC chips means better performance and much higher power consumption. Compared to the former AK DAC chip, the pin number doubled from 64 tothe die-size increased and the power consumption increased as well. AK is also the first AKM chip to be current driven and not fully voltage driven.

It eats current for breakfast and implementing two pieces of it means dissipating a lot more heat, using a much bigger power supply and doubling all the components around it. In simple words, it would use a much bigger case and the final assembled unit would be double the price.

Since Topping is trying to make high-performance DACs at affordable prices, for the moment a single AK design made a lot more sense to them. Who knows, maybe sometime in the future, dual-AK designs will be released from them as well.

I hope that will happen sooner than later. To let the DAC chip, breathe and work at its maximum potential two femtosecond crystal clocks from Accusilicon were used controlled by the Altera FPGA for the best results. I evaluated the D90 performance in a headphone and in a speaker-based system.This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

These options dont relate to frequency response of the filter, so they shouldnt behave any different with hi res or redbook. Though IME minimum phase filters slow or fast roll off sounded inferior to linear. Nov 23, Post 17 of Joined Mar 10, Messages Reaction score 8.
