DAC-01A Vacuum Tube Digital-to-Analog Converter/headphone amp
Add to Enquiry    

Note: After our years of ongoing research and development, the next generation of DAC-01A have been created - DAC-01A upgraded version, which adopts high-level decoder chip,

supports sample rates up to 192KHz and provides you with high performance of decoding. 


Product Description:

Based on the customers feedbacks and overwhelming demand, our engineers have upgraded the DAC-01 by redesigning the internal wiring and adjusting parameters. Now the new version is DAC-01A.
The DAC-01A 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. This is easy the best bang for the money. 
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 newer 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.
◆  (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.

Feedback from customers:
Ken Lam:   Just want to tell you that I am enjoying the sound of DAC-01 and 768B very much. 

                 The 768B produces very good sound when connect to my systems.Many thanks for

                 your help to get me the 2 boxes and all the trouble you've gone through, really appreciate that!
