The C9 from Cayin is the perfect accessory to your favorite headphones whenever you're on the go. The portable headphone amplifier has the option to switch between class A and AB, tube or solid state, high or low gain, and plenty of other options and features. Pair the C9 with you favorite source for rich, organic sounding high-fidelity audio.
Your choice of timbre: vacuum tubes or solid state. The C9 has a tailored-designed, fully balanced 40ch dual timbre circuit. It comes equipped with a quad set of Toshiba 2sk209 JFET and a pair of KORG Butube 6P1 double direct heated triodes. They're applicable to both single-ended and balanced phone output.
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.
Choose between high and low gain modes. MCU controlled and optimized automatically.
The C9 is designed with electronically controlled analog volume control with a 4-channel ALPS potentiometer with a pair of MUSES series low noise, low distortion resistance ladder stereo electronic volume.
Choose between line input and pre-amp input.
Line: receives fixed voltage audio signals from the line level output and functions as a headphone amplifier with local volume control.
Pre: receives variable voltage audio signals from the pre-amp output
The C9 is equipped with high-quality 4-ch JFET and BJT based fully balanced headphone amplification circuits for portable applications. To achieve the desired audio performance, the input signal is handled by a quad set of WIMA coupling capacitors and two matched pairs of LSK289 DUAL JFET differential amplifiers. The final output stage is composed of a matched quad set of doubled BJT in parallel, providing ample power for IEMs and headphones.
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.
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 provides +/- 8.4V direct power. Dedicated power protection and management to ensures 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.
