1. This Audio Device is designed and Developed by our engineers team over 4 years. This circuitary is based on PCM179X digital analog converter which has been improved, tuned and calibrated to make it performs at the best.
2. Sound Characteristics: Great Dynamic Range, Wide and Deep Soundstage, amazing details and sweet natural sound. Pair with high end headphones and audio components will let you enjoy the pleasure of high fidelity audio
3. The power supply is specially designed by using non-conventional technique, self developed T-Shaped RCR filtering network and also separate power supply section of each sections, to ensure power supply purity and naturalness of sound. Analog I/V conversion utilizing special developed I/V conversion module which comprise of audio grade JFET. The module is completely covered by metal case. With this module, sweet natural sound can be ensured with no listening fatigue.
4. Digital Signal Input go through into buffer which can effectively reduce jitter.
5. Power Supply utilizing custom made high performance EI transformer which is the basis of beautiful sound. After commutation, 3 pieces of ELNA Audio Grade Large Capacitors will do the filtering. After voltage stabilized will go through the filtering network which comprises of NICHICON MUSE Audio Grade Capacitors and high precision resistors. as much as 9 pieces of high speed capacitors were used into the digital circuit, such capacitors can only be found in a few European High End Audio Devices. Resistors comprises of DALE and KOA high precision resistor, some circuit uses the Western Electric High Class resistors.
6. The digital receiver of this item comprises of 74VHCU04 Hex Inverter and CS8414. Digital Analog converter is PCM1798, I/V conversion using self-developed JFET module, analog output stage using OPA604.
7. This item not only high performance DAC but also a high performance headphone amplifier too. The amp uses high current JRC4560D. the potentiometer is custom made in Taiwan. The DAC also has analog RCA output to connect to high end headphone amp or power amplifier for users who demand even higher performance.
8. Featuring dealy switch on capability and headphone protetion, to ensure safety of your headphones and speakers.
