Capacità

Well using audiophile resistor and capacitor specialized for audio products.We never lower our standard on high precision.

Power supply

USB receiver chip

Clock system

Built in TRIAD transformer from USA with features of high-efficiency and low-vibration, which supply sufficient power to audio DAC.With linear power supply and also powering by couples of ultra-low noise LDO for best performance.

USB receiver chip using the 2nd generation of XMOS USB audio solution XCrore200 XU208, support PCM sampling rate up to 768kHz,and DSD512,driver is exclusively customized and support DSD,which is very advanced in the audio range.

The clock system uses independent ultra-low color jitter and ultra-low phase noise crystal as audio clock.

DAC chip

BT4.2 Bluetooth module

High Power

Two pieces AK4452 used as DAC chip from AKM company.This 32bit DAC chip supports up to PCM768kHz,with low distortion, improve the integrity of the channel much, and more details can hear.

This unit uses advanced BT4.2 version,it is more stable and faster in transmission.It support apt-X (apt-X is a codec, or code/decode algorithm,that packs a digital audio signal into a smaller amount of data transmission bandwidth or data storage than the signal would otherwise occupy.lt’s a lossy (as opppsed to lossless)codec.It’S a fixed 4:1 compression ratio .

Operational Amplifier Using big power amp chip to ensure good performance.Low distortion,it is mostly more advanced than the OP amp which designs mainly for processing small signal.
