Portable Headphone Amplifier
Way more power behind new design
All-new appearance
All aluminum-alloy body and chassis increases metal texture and increases shielding from EM interference
Visual operation experience
New toggle switches are more reliable and easier to read and operate
Improved sound performance
Pre amplifier OPA1642: serves as the voltage amplifier, with great layering and medium and high frequency extension.
Power amplifier AD8397: serves as the current amplifier, with great control of low frequencies and smooth drive
Fully discrete bass circuit design
Bass On: Boosts bass effect without influencing the overall sound field
Bass Off: Bypasses bass circuit, decreases interference and noise floor so as to ensure the purity of the sound quality.
