Description

Top DAC chip

• Using the unit price which is over $15 ES9018K2M decoding. ES9018K2M is one of the best audio DAC, even higher than TI's flagship PCM1792, but also far ahead the WOLFSON WM8740 and the Cirrus Logic CS4398. This player used ES9018K2M professional version that ESS for the HIFI market, the version of price and performance used on the mobile phone market have also raised

High-precision temperature-compensated crystal

• 50mhz High temperature compensated crystal provide independent clock signal can reduce Period Jitter more than an order of magnitude ,compare with normally produced by the master to produce MCLK way is more accurate and stable, so that provide a reliable guarantee for the sound quality

Advanced op amp

• Several pieces of THD as low as 0.00002% LME49726 op amp as player IV and the buffer, after several system tuning and learn from the closed beta proposal to adopt opa1662 op-amp chip as a system OP, to further enhance the sound quality

Highest SNR

• The highest SNR index in the player world, high power amp, it is easy to deal with big headphones

Built-in line-out function

• Line output, can be connected to different amps to experience, a variety of play, consummately protect circuit, with the midpoint of the drift, switch squelch function, comprehensively protect headphones

Light and compact

• All CNC aluminum housing , the surface treatment using pearl powder oxidation process。Light and compact (48*100*16MM) dimension with the weight on more than 120G.

Rigorous power system

• High molecular solid capacitors possess environmental protection, low impedance, high temperature stability,  anti-high ripple and high reliability and other advantages, is the most high-end products in the electrolytic capacitor products, the filtering effect can reach 10 times more than the normal electrolytic capacitor, use this capacitor can reduce system background noise, provide more clean and high quality power supply

Extra-long Battery life

• The best PISEN high capacity rechargeable Li-ion battery,  the cycle life or more than 800 times, can easily change ,life time is more than 10 hours .
