K2 / Synchronous Clock Built-In Technology
K2 clock synthesizer Synchronous clock implantation technology synthesize local femtosecond clock or external 10M into audio master clock. Instead of the front-end clock source, DAC only uses local femtosecond clock or external 10M constant temperature clock source synthesis as the main clock. Therefore, the impart of the front-end signal source clock performance on the decoding link is greatly reduced. USB/IIS/AES/Coaxial/Optical/Bluetooth interface can also enjoy the performance improvement brought by synthesizer.
Excellent Performance ES9038pro Chip
Gustard X26 Pro features two pieces of ESS company flagship chip ES9038pro for decoding, each of that has a separate chip, meaning it can supply independent power completely and ground for excellent performance.
Independent R&D of DSP Digital Filter
The HiFi Audio Decoder adopts the high-performance digital filter solution which was developed on the Analog Device SHARC digital audio dedicated DSP platform. It is also equipped with a self-developed high-performance anti-aliasing noise algorithm. High-precision floating-point 64-bit operations are used in the key digital signal processing links. In order to reduce the aliasing noise in the digital domain audio band and achieve better sound quality performance, the high-performance decoder upscales and shapes the original digital audio stream signal.
Analog Low Pass Filter Circuit
Each discrete device only needs to consider its own performance without any restrictions, so it can perform fully every single component. The use of discrete devices is more flexible, not only because it is not integrated in the chip like integrated circuits and cannot be separated and changed but also it is more developable and relatively controllable for the distortion part. It can bring more variable sound styles to different decoding architecture.
CPLD Programmable Logic Chips
Digital integrated circuits are self-constructed with logic functions, clock management, 2nd PLL, digital shaping, DOP decoder, PCM/DSD depop switch and other exclusive technologies. All of these have laid a solid foundation for excellent sound quality.
MQA Full Decoding
The USB interface adopts XU216 chip of XMOS company and supports PCM768K DSD512 MQA full decoding.

Shipping Policy
Which countries do you ship to?
We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.
We cannot ship to addresses that are "PO boxes or APO/FPO".
*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.
How much does shipping cost?
We have two shipping methods - Standard Shipping and Express Shipping.
Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*.
*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.
Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for thetwo-way freightcharges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.
Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes.No refundwill be processed for such cases.Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments. Please contact us before placing an order, should you have any queries regarding shipping.
How long does it take to receive the order after it is placed?
