Switch between Class A and Class AB modes instantly. You can customize the sound signature to fit your personal listening preferences, music genres, and headphone pairings.

• Class A Mode: Low efficiency and low distortion. Musical, smooth, warm, and lush sounding.
• Class AB Mode: Higher efficiency and more dynamic. Clean, tight, great extension and slam.

DUAL GAIN CONTROL

Choose between high and low gain modes. MCU is controlled and optimized automatically.

• Primary Gain: Custom-designed 6dB voltage gain circuit.
• Secondary Gain: Gain circuit in electronic volume control.

The C9 is designed with electronically controlled analogue volume control with a 4-channel ALPS potentiometer with a pair of MUSES series low noise, low distortion resistance ladder stereo electronic volume

EFFECTIVE HEAT DISSIPATION

Cayin attached PBS (Pyrolytic Graphic Sheets) to components inside the C9 amplifier that generate the most heat. This was carefully designed for effective heat management to divert and dissipate heat energy efficiently, right down to the placement of the components themselves. The C9 portable headphone amplifier maintains consistently low temperatures due to this design.

REPLACEABLE BATTERY TRAY

The C9 amplifier contains a reliable power supply from 4x Sony VTC6 3000mAH 18560 Lithium batteries, with 8-12 mOhm low internal resistance and 30A maximum continuous discharge. Four batteries in series provide +/- 8.4V direct power. Dedicated power protection and management to ensure that all four batteries will be fully charged at the same pace. The C9 is compatible with QC3.9 and PD-compatible Fast Charging through the USB Type-C interface with an LED indicator to display charging and battery capacity status.
