E500 Headphone Amplifier DAC Assembled Field Effect Tube High Transparency Super Pure Sound Quality

E500 Headphone Amplifier DAC Assembled Field Effect Tube High Transparency Super Pure Sound Quality

Features:
- The circuit of this headphone amp based on that for Dynalo.
- Highly transparent and extremely pure sound quality.
- There is ample driving force, the sound quality of this machine is also impressive, pure texture without any impurities. It boasts high-quality sound, high and low gain.
- It can drive various HiFi headphones, showing different timbres. The highly transparent sound is also the highlight.
- Structure: transformer-power supply-amplifying circuit. A thermal bridge is shared between the power supply part and the amplifying circuit, and the thermal bridge also plays a role in isolating interference. Input differential amplifier tube uses a premium field effect tube. The power supply part uses two imported ring-shaped transformers and HiFi capacitors.
