Make the things better

 

HPA-2 CLASSIC headphone amplifier is the improved model of HPA-2, the optimized circuit design, new style appearance, exquisite processing technology and excellent performance to make it better.

 

Details everywhere

 

The high-brightness chamfering edge design of front panel, ultrahigh speeds revolving cutting tools elaborately carved out the mirror-like gloss edge on front panel, further improve the visual texture. The knurling design of volume knob to add the friction of the finger contact area can get better grip compare with polishing surface treatment, red mark on volume is more clear and distinguishable.

 

More choices More enjoyments

 

The new gain control function, switching the gain switch on the rear panel to adjust output gain, two sections gains to match different headphones.

 

Hi-Res Compatibility

 

The new design of USB module is used XMOS U series chip and CS4398 high-performance D/A chip, support PCM-24bit/192kHz and DSD-2.8MHz/5.6MHz signal playback, not only DoP and ASIO Native two DSD playback methods, but also can be used with the iOS and the most android devices.

 

Functional & Safe

 

Class A work mode can feature it easily to drive all kinds of low sensitivity dynamic headphones; can be used as a preamplifier. The headphone protection function and power on/off noise elimination function to prevent the wrong voltage to damage your headphones and brings you the better user experience.

 

Performance heart & Simple appearance

 

Cherry-pick every components, the ALPS 27 type volume potentiometer, WIMA/Nichicon audio grade capacitances, audio dedicated power supply transformer, and precision non-inductive resistances, all of these selective components to ensure get the best playback performance from HPA-2 CLASSIC.
