.........GLD1.0 is a digital player that is completely different from current digital players on the market. It does not use USB interfaces for internal data transmission, nor does it send audio data through a USB interface. In short, it does not rely on the USB audio protocol, because the USB audio protocol allows data errors and permits the discarding of erroneous data packets. .................................Instead, GLD1.0 uses an internal high-speed serial bus, PCIe, to output audio data in a synchronous manner. The PCIe protocol does not allow data errors or packet loss, and the data is transmitted directly from the CPU to the next device without intermediate steps. As a result, no audio data errors or losses occur. Additionally, GLD1.0 uses a complex clock architecture to ensure synchronized data output, achieving the highest level of digital player performance, often referred to as the "ceiling" level. ...................................In order to output audio data and clock signals with the highest quality, GLD1.0 also features the proprietary "POW" interface, which uses optical fiber to output data and coaxial cables to output the clock. This groundbreaking invention has created a new model for digital players...................................... Hong Kong's "Audiotechnique" magazine described the GLD1.0 as "a revolutionary design that opens up a new digital audio frontier."

9i-806 "Little Silver Fox" headphone Amp is simplified version of 9i-906 :Silver Fosx". Most Advantages of 9i-906 have been preserved but the price is lower than it. Very good value for money.

. DSDAC 1.0 deluxe model is a new product which was developed on the basis of the standard model by optimizing the clock system and making major modifications to the circuit. It is different from the ordinary DAC. Its high-precision DSD frequency raising algorithm solves the playback problem of dsd64 perfectly. . The synchronous direct clock technology enables the built-in femtosecond clock to be transmitted to the shift register directly without any process, so that the femtosecond performance can directly improve the analog signal quality. The clock blocking technology can isolates the clock of pre-device completely , so that the clock of the pre-device no longer becomes a factor affecting the sound quality.

. DSDAC1.0 is a high-performance audio DAC based on DSD theory. It is completely different from ordinary DAC because it has many original technologies. It does not use conventional chips for DA conversion but FPGA and discrete components for digital processing . . DSDAC1.0 can increase the frequency of all input data including PCM or dsd64 to dsd1024. If the input data is higher than the dsd128, you can also output it directly without increasing. DSD frequency raising algorithm is a very complex mathematical process, DSDAC1.0 did a good job. . One year after the standard model was launched，the super clock model was launched. Performance is futher improved

. The 9i-906 headphone amplifier is nicknamed the "Silver Fox". Its purpose is to drive "monster" headphones. The circuit structure is derived from a high performance power amplifiers. After many redesigns and adjustments, the "Silver Fox" has finally become an excellent headphone amplifier. It not only has the advantage of high analysis, but also features high density and neutrality. The sound is musical. It has outstanding driving performance and can drive low sensitivity headphones. It is one of the best in its class. . . . Whether high or low sensitivity, high or low impedance, moving coil headphones or flat panel headphones, the "Silver Fox" is able to match them all with its superb driving ability and quality. Compared to ordinary headphone amplifiers, the Silver Fox allows headphones to fully reveal their characteristics.
