Product Details



D3 can input RCA coaxial, BNC coaxial, fiber optic signal, supports a wide 16bit-24bit, 32kHz-192kHz;
D3 can connect the computer to become a good external USB sound card, USB supported range of up to 24bit/96kHz, through the drive can support ASIO;
In addition, D3 also take into account the AUX input, can be used as pure amp or preamp to use;
CS8416 + CS4398 + OPA2134 full HIFI devices finely tuned to get the perfect sound;
Amp output voltage swing of up to 19.2 volts, easily drive 600 ohm impedance headphones;
D3 with CNC precision machining aluminum shell and solid aluminum knobs, texture, feel better.


D3 features: 
1, the whole band minimum distortion of only 0.0005%, which is more than ten million class professional audio test instrument measured

2, coaxial decoder, fiber optic decoder, external USB sound card, amp, pre-integrated design, a machine can solve the majority of users HIFI needs; 
3, using the Cirrus Logic CS8416 coaxial receivers with top decoder CS4398 combination, to achieve 16bit-24bit, 32kHz-192kHz full support; 
4, built SOLO amp, the output swing high, regardless of driving high impedance headphones or as a pre-use are adequate; 
5, full intelligent control, display, with only two buttons you can control all functions; 
6, USB interface, using Taiwan's TE7022L TENOR program supports up to 24bit/96kHz, more can be achieved with the driver ASIO. 
7, abandon the traditional mechanical switches, the introduction of FET switch for the machine to reduce the internal resistance of the power supply while avoiding the circuitous routing; 
8, sound mute switch circuitry, maximizing the impact of reducing the switching machine sound; 
9, aluminum chassis using CNC machining centers precision machining, giving you superior visual impact and operation of hand; 
10, is widely recognized quality devices using fans to create the best quality and performance, such as: Japan, KOA resistors, Germany WIMA capacitors, Germany's Siemens capacitors, Japanese capacitors ...... nichicon Audiophile. 
11 thick EPE packaging, even with fiery couriers can ensure that no damage to the interior.
12 overall chassis with brushed appearance while in the tank sandblasting process, making D3 also has two kinds of texture
13.4 LED instructions respectively four kinds of digital input while flashing to indicate the conventional Unlock instructions.
14 As the built-in MCU control, intelligent machine operation / display, two small button you can control all functions.
15 extension products using original toroidal power indicator light, although this design has been many brands Reference imitation, but still classic.
16 rich input and output interface. Extensive use gold-plated interface to ensure smooth signal transmission.
17 All logo laser engraving process, durable do not fade
