NANO USB DAC Headphone AMP

Features:

1) innovative use of OP expansion flow of a single power switch to dual power supply design, using the virtual machine to a dual power supply design, the whole high-noise ratio
 
2) digital integrated circuits on a single switch dual power supply based on the use of two regulated power supply, ensure that the digital part of a good power supply
 
3) Use high-quality gold-plated FR4 ​​4-layer board design, 4-layer design to provide a good line native environment
 
4) the use of OP + BUF amp design framework, and the headphones into the line-out will automatically cut off
 
5) nichicon and WIMA capacitors use special sound, precision chip resistor 1% 4-digit resistance
 
6) The machine does not use the computer's power supply, all multi-level IC all external DC voltage
 
7) The volume of direct control by the computer! All through the analog line-out design, PCM2707 output coupling capacitor, after no one, directly to the output part of the
