SMSL D1 Flagship Audio DAC

S.M.S.L. D1 Flagship Audio DAC

• Used 2 piece of DAC chips ES9038PRO, one -piece split power supply

• D1's clock system consists of 3 ultra-low phase noise active crystal oscillator and CPLD logic system! CPLD uses the high-speed CPLD-EPM240T100C5N manufactured by ALTERA, an American chip company under the umbrella of Intel Corporation. Its logic speed reaches 300MHz, together with excellent clock algorithms, the JTTER of the entire clock system is as low as 5ps!

• The USB program of D1 is our new second generation XMOS program, and with the above clock system and asynchronous transmission, JITTER is extremely low! Supports PCM32-bit 768KHz and DSD64-DSD512!

• D1's regulated power supply circuit is specially designed by us. The use of transistors constitutes a constant current source, which has a more stable temperature characteristic than a constant current source constructed using a conventional JFET!

• The ultra-low noise toroidal transformer ordered directly by NORATEL UK Co., Ltd. Its noise is 1/3 of an ordinary domestic transformer, however the efficiency is 1.3 times of a domestic transformer. At the same time, it uses a potting technology to make it less vibration, fixed better, longer life!

VMV high-end pure DAC-D1

 

 

• High-quality electronic components
• The capacitor of D1 is 100% imported, and it has been screened. In order to ensure the performance, the ECHU of Panasonic Japan is used. This capacitor has the shortest audio path and the smallest interference area! The resistance of the audio part is all used imported VISHAY's MELF high-precision low temperature drift resistor!

 

 

• Double ES9038PRO Chips
• ES9038PRO, the status of this chip is undoubtedly, its official dynamic range up to 140dB (D1 measured more than 131dB) this performance is close to the value of the digital signal itself! This is not only a very powerful DAC chip today, but also it's a very expensive audio DAC chip! Comparable to Intel's new computer CPU, D1 abnormally use two, really worth it!
