Cayin IHA-8

Cayin iHA-8 | Desktop Headphone Amplifier

Pure Class A • Balanced Power • Compact Precision

The Cayin iHA-8 is a fully balanced Class A desktop headphone amplifier engineered for audiophiles who demand precision, power, and musicality. Combining advanced circuit design with robust component architecture, it delivers unmatched clarity, dynamics, and tonal balance in a compact form factor. Ideal for both desktop and home audio setups, the iHA-8 blends modern versatility with true high-end craftsmanship.

Pure Class A Headphone Amplification

At its core, the iHA-8 employs a four-channel discrete pure Class A buffer circuit featuring low-noise TI Op-Amps and dual Toshiba JFETs per channel. The design minimizes distortion and noise while increasing current output for enhanced driving power.
Powered by Vishay MOSFETs in a three-stage Class A configuration, it ensures a stable DC output and adaptive performance, providing rich, transparent, and natural sound across all headphone types.

Precision Volume Control

For precise volume management, Cayin integrates a custom ALPS step potentiometer with dual 130-step JRC MUSES72320V electronic volume chips.
While electronically managed, the adjustment remains fully analog — guaranteeing stability, balance, and smooth volume transitions. This ensures consistent channel accuracy and a refined tactile control experience.

High-Stability Power Supply

Engineered with premium-grade components, the iHA-8 offers powerful and noise-free performance:

• 70W low-leakage toroidal transformer for stable, efficient power delivery

• 50,000μF Nichicon capacitors for ultra-clean current and dynamic headroom

• BYV79E rectifier diodes for fast recovery and reduced power noise

• Independent power regulation for the voltage amplification and HeadAmp output stages ensures clean, accurate signal delivery with reduced interference

Compact and Elegant Design

Compact yet powerful, the iHA-8 complements Cayin’s i-series lineup (iDAC-8 & iDAP-8).
Its CNC-machined aluminum chassis with fine sandblasting and anodized finish offers durability and aesthetic refinement. Designed for versatility, it fits perfectly into any modern desktop or home setup while maintaining low heat and minimal footprint.

Versatile Connectivity

The iHA-8 supports multiple connections for flexible pairing:

• Headphone Outputs: 6.35mm Single-Ended, 4.4mm Balanced, and 4-pin XLR Balanced

• Line Inputs: RCA and XLR options for seamless integration with DACs, CD players, or streamers

Comprehensive Protection Circuitry

A monolithic protection IC safeguards your equipment with:

• Output DC detection

• Power-on delay squelch

• Power-off noise cancellation

• Overcurrent and overload protection

This ensures long-term reliability and consistent performance under all conditions.
