Cayin - Pearl 30i - 30th Anniversary Tube Amplifier Review celebrates three decades of Cayin's tube amplifier expertise with a blend of warm tonality, robust power and elegant design. As a dual-cabinet integrated amplifier with a separate power supply system, the Pearl 30i sets new benchmarks for dynamic range, transient response and signal purity.

Stunning Design & Build Quality

The Pearl 30i’s two-cabinet architecture houses the amplifier unit and power supply unit separately, ensuring minimal magnetic interference and optimised S/N ratio. Each channel boasts its own high-voltage (800 W) and low-voltage (200 W) transformers, culminating in a colossal 2000 W total power reservoir for uncompromised dynamics.

Customised 6N silver-plated copper cables link the units, preserving signal fidelity and lowering distortion. The high-rigidity chassis with advanced vibration-damping treatment completes a build that’s as durable as it is beautiful.

Sound Performance: Warmth Meets Authority

At its heart are four Tung-Sol KT170 power tubes per channel in a Class AB push-pull topology. In ultralinear mode you’ll enjoy 230 W per channel, or switch to triode mode for 145 W of luxurious warmth. Triode delivers tender, harmonically rich vocals, while ultralinear offers punchy dynamics and extended bandwidth.
