XiangSheng DAC-01A DAC Headphone Amplifier USB with Bluetooth Receiver Audio AMP Black Panel

Headphone Amplifier Description:
The DAC-01A DAC Headphone Amplifier stands out with its high fidelity vacuum tube output . With no less than five sources signal inputs for selecting : DVD/CD, AUX, coaxial, optical and USB input. 

The DAC-01A lets you “upgrade” the music listening experience, for any type audio setup, from computer-based systems, to network music devices, or standard CD/DVD etc. Just plug it into your existed setup and enjoy the superior high end sound quality.

This is a new design so not like the old Tube DAC. 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.

Headphone Amplifier Features:
- 5 sets of inputs: including 2 sets of analog RCA inputs(DVD/CD, AUX), (1) coaxial, (1) optical and (1) USB input.
- 2 sets of RCA outputs – transistor and vacuum tube.
- Built-in headphone amplifier: allows you to enjoy music with privacy. Great power, music layers and details.
- Genuine imported processing chip. 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.
- Having two RCA analogy un-balance output(Normal Output and Tube Output), can be connected to transistor amplifier and tube amplifiers.
- The volume potentiometer does not control volume on the line outputs, just the headphone.
