An android based media player product with many funtions. It can play not only local music but also online, such as Aairplay and Tidal support.

. .9i-90SA Pro （"Lark" second Generation ）DAC/headphone Amp/Pre Amp， It is a low-priced product and carries some high-level audio technology and practical functions. Although it is cheap but its audio performance is close to that of high end products. It is good choice for most Junior enthusiast.

. 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-AD series media player adopts the 88de3010 scheme of Marvell as the main control and has high-definition video function(2K). Because of QDEO technology and two high-end audio DSPs inside, its video quality is very good as well as audio quality. After we redesigned it, it can receive external clock. With excellent audio and video performance, 9i-ad has achieved very good market performance.

. .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. It has strong competitiveness

. .9i-ADM 8 channel HiFi media player is designed for multi-channel HiFi. It adopts the 88de3010 scheme of Marvell as the main control and has high-definition video function(2K). Because of QDEO technology and two high-end audio DSPs inside, its video quality is very good as well as audio quality. After we redesigned it, it can receive external clock. . .The difference between 9i-ADM and 9i-AD is that 9i-ADM has 8 ch analog output but 9i-AD only has two.

. .9i-ES/ESA is a media player designed for desktop hifi system. It is a reduced version of the 9i-AD Black Gold Ultimate Model. . .9i-ESA is a model with headphone amplifier.

. The nickname of 9i-906 headphone amplifier is "silver fox". Purpose is to drive “monster” headphones. Its circuit architecture originates from a large power amplifier. When many redesigns for electrical characteristics and adjustments of sound style were completed, "silver fox" became a wonderful headphone Amp. High analytical, high density and neutral without tendency, especially power driving fprce, make it leader in similar products. . Whether 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 quality. It can show the characteristics of headphone more than normal headphone amp.

9i-810 is simplified from 9i-908 and the sound is re-tuned.

9i-908 dual-channel power amplifier, 2*250W power, has strong driving capacity, can drive large loudspeakers.
