DSDAC 1.0 (deluxe model)

DSDAC 1.0 deluxe model is a new product developed on the basis of the standard model by optimizing the clock system and making major modifications to the circuit. Like the Standard Version, it is different from the ordinary DAC. It opens up a new mode of audio DAC with a number of original technologies. 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, so that the femtosecond performance can directly improve the analog signal quality. The clock blocking technology completely isolates the front-end clock, so that the clock of the front-end no longer becomes a factor affecting the sound quality.

DSDAC 1.0 (standard model / Super clock model)

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 dsd128 to dsd1024. If the input data is higher than the dsd128, you can also output it directly without increasing the frequency. DSD frequency raising algorithm is a very complex mathematical process, dsdac1.0 does a good job. One year after the standard model was launched,the super clock model was launched. Performance is futher improved

9i-92SA III(Third Generation) DAC/headphone Amp/Pre Amp

Due to success of 9i-92SA " golden thrush" second and first generation the third generation was born but it's DAC chip was changed from AK4497 to ESS9038Pro . As a general rule the performance of ESS DAC chip is highly analytical and dynamic but it's sound is a little hard, so there are many special adjustment have applied to the Third Generation and got good effort . It already has many users and has very good comments. In this level of product it has strong competitiveness

9i-906 "Silver Fox" Headphone Amplifier

The nickname of 9i-906 headphone amplifier is "silver fox", which is designed to drive monster level headphones. Its circuit architecture originates from the large power amplifier. When many redesigns for electrical characteristics and adjustments of sound style were completed it became a wonderful headphone Amp. Its sound style is high analytical, high density and neutral without tendency. As a high-end audio equipment, neutral is the most important characteristics. Whether it is high sensitivity or low ,high resistance or low , dynamic earphone or flat panel headset, "silver fox" can adapts to them by it's super driving ability and outstanding quality. It can show the characteristics of headphone more than normal headphone amp.

9i-92SA (Second generation) DAC/headphone Amp/Pre Amp

Based on the 9i-92sa "golden thrush" first generation, include the second optimizing of the DAC output buffer , redesign of the earphone circuit and learning from some design of dsdac1.0 . The audio performance of the Second Generation is significantly better than the First. The process level and the appearance has been greatly improved, the height has been reduced. The voice style of the Second Generation has been widely recognized and is known as the representative model within 10000 yuan. The Second Generation has made great progress in the purity and density of sound. At the same time it has maintained the outstanding characteristics of musicality like the first generation and has strong competitiveness.
