Pearl 30i: The 30th Anniversary Tube Amplifier – A High-End Integrated Amplifier for Audiophiles

The Pearl 30i, a limited edition 30th Anniversary Tube Amplifier, is a meticulously crafted integrated amplifier that features a separate amplifier unit and power supply unit. Designed to offer unparalleled sound quality and reliability, the Pearl 30i is equipped with four power transformers—two for each channel—ensuring superior performance for both left and right channels. Each channel benefits from a dedicated high voltage and low voltage power supply, delivering 2000 watts of total power, ensuring optimal dynamic and transient response during music playback.

Superior Power Supply Design for Unmatched Performance

The Power Supply Unit of the Pearl 30i consists of two separate channels, each with an 800-watt high voltage and 200-watt low voltage power supply. This combination guarantees exceptional power output and efficiency, with a total power rating of 2000 watts to ensure dynamic range and musical accuracy.

To maximise signal-to-noise ratio (S/N ratio) and reduce magnetic interference, the amplifier and power supply units are housed in high-rigidity chassis structures with top-tier vibration damping treatment. This design allows the units to be positioned either side-by-side or stacked vertically, offering flexibility while maintaining the best possible sound quality.

Customised Power Cables for Optimal Signal Transmission

The Pearl 30i features customised power cables that connect the amplifier unit to the power supply unit. These cables use 6N copper silver-plated wire, providing a superior connection for both left and right channels with four separate cables for each.

Tung-Sol KT170 Power Tubes for Superior Sound

At the heart of the Pearl 30i are Tung-Sol KT170 power tubes, which form the foundation of its incredible sound performance. In ultra-linear mode, the Pearl 30i delivers 230 watts per channel, and in triode mode, it outputs 145 watts per channel. The amplifier uses four KT170 tubes per channel in a Class AB push-pull configuration, ensuring powerful yet refined sound.

Dynamic Auto-Bias for Tube Longevity and Consistency

The Dynamic Auto-Bias system in the Pearl 30i ensures that the KT170 power tubes are automatically biased, eliminating the need for manual adjustments when tubes are changed. This auto-bias system not only extends the lifespan of the power tubes but also ensures they remain well-matched, providing long-term reliability and consistent performance.

Dual-Operation Modes: Triode and Ultralinear

The Pearl 30i offers two operation modes that can be switched instantly to deliver distinct sound signatures:

• Triode Mode: Known for its smooth, harmonic-rich sound, ideal for vocal and instrumental music, offering a tender and warm listening experience.

• Ultralinear Mode: Delivers more power and extension with a clean, energetic sound that excels in dynamic and punchy music.

Dual Timbres for Dynamic and Soft Sounds

The Pearl 30i incorporates a unique design that allows you to adjust the operation current of the KT170 power tubes, offering two distinct timbres:

• Dynamic Timbre: Perfect for music that requires energy and punch.

• Soft Timbre: Ideal for more delicate and nuanced listening.

Premium Components for the Ultimate Audiophile Experience

The Pearl 30i features several high-end components that ensure exceptional sound quality:

• JRC MUSES 72320V Electric Volume Controller: A high-precision volume control that provides low noise, low distortion, and linear volume adjustment.

• Custom-Wound Output Transformers: Made with Z11 audio-grade silicone steel sheets, these transformers guarantee minimal signal loss and superior low and high-frequency response.

• AudioCapX PPFXS Coupling Capacitors: Used for the best signal coupling with minimal distortion.

• Silver-Plated Signal Wires: Ensure stable signal transfer with reduced attenuation and interference.

• Nichicon Audio-Grade Filter Capacitors: Contribute to cleaner power and more accurate audio reproduction.

Versatile Inputs & Outputs for Enhanced Connectivity

The Pearl 30i provides a wide range of input and output options to integrate seamlessly into various audio setups:

• Four pairs of line inputs: Including one pair of balanced XLR inputs for optimal connectivity with balanced audio systems.

• Pre-In Inputs (RCA & XLR): Allow you to connect an external preamplifier and use the Pearl 30i as a dedicated power amplifier.

• Subwoofer Output: A dedicated sub-output allows you to connect a subwoofer for extended bass response.

• Speaker Terminals: Compatible with 4-ohm and 8-ohm speakers, ensuring compatibility with various speaker systems.

Cutting-Edge Protection Features

The Pearl 30i includes a range of advanced protection circuits and power-on timing to ensure optimal performance and safety:

• 60-second time delay during power-on.

• Soft start circuit for smooth power-up.

• BMI function to protect the amplifier under extreme conditions.
