Cayin - iHA-8

The Cayin iHA-8 features a fully balanced discrete circuit. The four-channel differential circuit design equips TI low-noise mono Opamps and Toshiba audio-grade JFETs connected in parallel with a constant current source for each channel. This design ensures low noise, low distortion, high current and better driving ability. The Cayin iHA-8 also incorporates Vishay power MOSFETs for a three-stage large bias current. It also includes a DC offset voltage servo circuit to maintain a stable output DC offset voltage of 0V. It has built-in adaptive power, gain and quiescent current switching circuits that enhance iHA-8's overall performance, delivering an exceptional music listening experience. The Ultimate Hyper Mode maximizes the headphone amplification circuit's performance by adjusting and improving the static operating current and voltage. This mode increases output power and gain while preserving the pure Class A state, resulting in a more pristine, transparent sound with a well-defined and dynamic soundstage.

The Cayin iHA-8 offers preamp and line-level input options with volume control capabilities. When Line input is selected, it allows the Cayin iHA-8 to function as an integrated headphone amplifier. In Pre input, it operates as a pure power amplifier when connected to a front-end DAC with preamplifier functionality. Cayin has implemented a precise volume control circuit to deliver exceptional sound performance in your music listening experience. It utilizes an ALPS-customized step potentiometer in combination with high-end 130-step electronic volume chips and the JRC MUSES72320V. Despite electronic control, the volume adjustment occurs purely in the analog part. This meticulous design provides a delicate feel when adjusting the volume and ensures stable and precise volume control, enhancing the overall listening experience.

The Cayin iHA-8 provides versatile output and input options, catering to different headphone preferences and audio equipment. It provides three distinct output options - 6.35mm single-ended, 4.4mm balanced and 4-pin XLR balanced, allowing users to choose headphones according to their mood and preferences. The Cayin iHA-8 also includes balanced and single-ended dual inputs, facilitating easy connectivity with CD players, desktop decoders, portable players and other audio sources using XLR or RCA connectors. This Cayin iHA-8 ensures compatibility with different setups and enhances convenience. Overall, the Cayin iHA-8 guarantees a satisfying and enjoyable music-listening experience, regardless of headphone choice or audio source.

The Cayin iHA-8 is carefully designed with a robust power supply system to match its Class-A amplifier identification. This system features carefully selected premium components to complement its advanced technology. It includes a 70W high-power low magnetic leakage toroidal power transformer, a 50,000uF Nichicon main filter capacitor and BYV79E ultra-fast recovery rectifier diodes to ensure efficient and stable power delivery. The Cayin iHA-8 integrates a monolithic Protector IC alongside its high-power components to provide comprehensive protection. This protection system safeguards your setup by detecting output DC, implementing power-on delay squelch and power-off noise cancellation, and offering overcurrent/overload protection, ensuring the safety of the power amplifier circuit and headphones throughout every stage of operation.

Cayin has designed the iHA-8 to seamlessly blend with the Cayin i-series lineup, ensuring a cohesive and harmonious aesthetic. Its design features an exquisite and compact structure that complements the aesthetics of its companions, the iDAC-8 DAC and the iDAP-8 digital streamer. This similar design language across the i-series products enhances their visual appeal and ensures an elevated user experience. Whether used individually or in combination, each product maintains its unique functionality while harmonizing effortlessly within a complete audio setup. This design approach reflects Cayin's commitment to craftsmanship and attention to detail but also offers users the flexibility to create personalized audio configurations tailored to their preferences and needs.
