Cayin IHA-8: Advanced Power and Superior Listening Experience

The Cayin IHA-8, an advanced model of the renowned IHA-6, is a stationary Class A amplifier. Equipped with four JFET channels and dual gain adjustment (high and low), this device takes the listening experience to a new level.

Versatile Connectivity and Audio Modes

It offers multiple headphone output options including XLR-4, 4.4mm and 6.35mm. Plus, it features the innovative Hyper Ultimate mode for richer, more dynamic sound reproduction.

Compact and Powerful

Despite its compact size, the IHA-8 incorporates the best internal components to ensure superior sound quality and a noticeable improvement in the performance of your favourite headphones.

Pure Class A Amplification

Utilises a pure Class A amplifier circuit with four channels, reducing noise and distortion while increasing current and driveability for exceptional listening.

Hyper Mode Innovation

Hyper Mode maximises the performance of the amplifier circuit, adjusting current and voltage in Class A status to improve power output and gain, resulting in clearer sound and a well-defined soundstage.

Full Connectivity

The IHA-8 provides three output options for the most popular headphones on the market, adapting to any listening need. In addition, it allows for balanced and single-ended connections with XLR and RCA inputs.

Precise Volume Control

The volume control system includes a custom ALPS step potentiometer and JRC MUSES7320V electronic volume chips, allowing fine and precise adjustments in the analogue domain.

Robust Power Supply

The design includes a discrete high-current, high-dynamic voltage stabiliser circuit, ensuring a stable and efficient power supply for the amplifier and its circuitry.

Comprehensive Protection

A built-in protection system ensures the safety of the amplifier and headphones through various measures such as DC detection, delay squelch and overcurrent protection.

Exquisite and Functional Design 

The IHA-8 is not only functional, but also aesthetically appealing with a compact design that integrates seamlessly with other audio devices, delivering optimal and durable performance.
