We can Declare the Value of the Order as Customer's Remark!!!
Notice: The upgraded version of XiangSheng DAC-02A DAC use the hiend part like below, and have nicer sound. American DALE resistance, Japanese light tone resistance, ELNA capacitors, Sanyo capacitors, Taiwan solid British electrolysis, BC capacitance, The ruby rubycon capacitor France Suren capacitance, American GE5670 vacuum tube, OPA2604AP with gold-plated seat. Product Description: High-resolution digital to analogue audio converter with superior audio dynamic performance for consumer audio and musical applications. (4) sets of digital inputs: (1) coaxial, (1) optical, (1) USB and (1) BNC input. (2) sets of RCA outputs –The unit have two output, one with transistor and one with single 6N3 vacuum tube. So you can change the two output to find more fun. You can compare the sound between the two output then find out which can match you listen taste. Built-in headphone amplifier: allows you to enjoy music with privacy. Great power, music layers and details. Genuine imported processing chip. Produced elaborate Main Amplifier Boad adopt "Double-Sided Board" design. All resistors and capacitors are audiophile grade to ensure sound quality. Key parts are from Germany and Taiwan etc. R-shape high efficiency transformer. Separate power supply rectification to analog and digital circuits. Gold coated RCA connectors and coaxial connector. Vacuum tube output use well-known Chinese 6N3 tube. It can be replaced with 5670 type of tube. Brushed aluminum faceplate, with all metal buttons and knobs, plus blue LED indicator light. The volume potentiometer does not control volume on the line outputs, just the headphone. When there is no signal input, it'll become mute automatically. Parameter: Tube Used: 6N3 ( can be replaced with 5670 tube) Digital Audio Inputs: (1) coaxial, (1) optical, (1) USB and (1) BNC input. Stereo Audio Outputs: 2 analog stereo outputs via RCA Left/Right channel: Normal Output and Tube Output.
