DAC-01A Version 9 USB Decoder SA9023 Sampling Frequency 24Bit/96KHz Headphone Amplifier

Product Description


Model: Version 9 with SA9023 USB Decoder Sampling Rate 24Bit/96KHz
- 5 Signal Input Switching: analog part: DVD/CD, AUX; digital part: coaxial, optical fiber, USB. It is switched with IC relay.
- 2 Stereo RCA Unbalanced Outputs: normal output and tube buffer output, which enables it be compatible with tube amplifiers or transistor amplifiers for different effects.
- Amp Main Board: adopts double panel design with fine workmanship
- Headphone Amplifier Output: This circuit refers to the classic circuit.It adopts integrated power amplifier + discrete parts in the power-to-tube expansion form. The amp final stage current amplification uses the emitter follower. When the headphone is driven, the current is not required as large as that of a power amplifier, so the value of the emitter resistance does not have to be small, which can increase the final feedback, reduce distortion, and improve stability. And the Jubel network is added to prevent high frequency self-oscillation.
    In order to protect the earphone, an output resistor and an output capacitor are added. In order to ensure the sense of hearing, a large-capacity electrolytic parallel small-capacity monolithic capacitor is used to make the high-middle and low-end signal coupling smooth.
- When the digital part is not input, it is automatically muted.
- The output part of the tube adopts the domestic famous tube with medium frequency and warmth: 6N3 (foreign replacement model 5670), the tone is soft and beautiful. Both the high voltage and the filament are regulated by DC power.
- The earphone push and isolation buffer adopts National Semiconductor's LF353N (field effect input dual op amp, warm and delicate), and the NE5532 op amp was called the four major op amps. You can upgrade your own advanced fever op amps by yourself.
- Resistors and Capacitors: are assembled with high-quality discrete heating components, which ensures the sound quality and facilitates the replacement of components. It features pure sound quality, high resolution, wide sound filed. 
- Knobs and Buttons: are all made of metal for durability. 
- Indicator Light: blue LED light  
- Using R-type transformer with superior performance (usually only for high-end equipment), although the cost is significantly higher than that of ring and square transformers, it has high efficiency and small magnetic leakage.
- Digital part and analog part independent rectification and filtering power supply to reduce interference.
- The volume potentiometer is made in Taiwan.
- The analog input RCA port, the line output RCA port, and the coaxial port are all gold-plated to reduce the contact resistance.
