Lyrebird EL84/4 Integrated Amplifier

Lyrebird EL84/4 Tube Amplifier Showcases Handcrafted Australian Excellence

The Lyrebird EL84/4 Integrated Tube Amplifier is a handcrafted valve-based amplifier delivering warm analogue tone and detailed audio resolution. Designed and assembled entirely in Adelaide, South Australia, this high-fidelity integrated amplifier is the debut model from Lyrebird Amplification. It blends meticulous design, premium component selection, and a distinctly analogue signal path to offer an emotionally engaging listening experience, built to outlast and outperform mass-produced alternatives.

Lyrebird EL84/4 Prioritises Signal Purity with Zero Feedback Topology

Lyrebird EL84/4 Integrated Tube Amplifier is engineered for tonal integrity. At its core lies a pure analogue signal path with zero feedback and zero PCBs, enabling uncoloured musical reproduction. Each amplifier is point-to-point wired by a Soviet-trained technician with over five decades of circuit-building experience. This artisan-led construction ensures ultra-clean signal flow and class-leading electrical reliability. The design implements custom-made output and power transformers, manufactured in Adelaide to tight tolerances, with dedicated fuse protection ensuring transformer longevity.

This dual-mono integrated design offers independent volume control for each channel, allowing users to fine-tune the stereo image or compensate for imbalances in speaker placement or room acoustics. Tone controls are completely defeatable, preserving signal purity for audio purists while remaining available for more tailored listening when needed.

Lyrebird EL84/4 Produces Lush, Expressive EL84 Sonics with Surprising Drive

Lyrebird EL84/4 Tube Amplifier is voiced to make the most of the EL84 pentode valves’ renowned musicality. Its sonic signature balances sparkling high frequencies, vivid and sweet midrange articulation, and unexpectedly authoritative bass dynamics. Even at 20 watts per channel into 8 ohms, the EL84/4 drives medium and low-sensitivity speakers with an ease that belies its compact tube complement.

Thanks to precision-matched valves operating well below stress thresholds, the amplifier delivers consistent sonic performance over time, with low distortion (less than 0.1% at 1 watt) and an impressively quiet background (better than -87dB SNR). The result is a deeply immersive soundstage, where vocals and instruments breathe with natural realism and space.

Lyrebird EL84/4 Features Artisan Craftsmanship and Local Component Sourcing

Lyrebird EL84/4 Valve Integrated Amplifier is constructed using a rigorous selection process for every component. Each resistor, capacitor, transformer and valve socket is individually tested to exceed design specifications. Wherever possible, materials are sourced from Australian manufacturers, supporting local industries while ensuring rapid availability of replacement parts or upgrades.

The amplifier’s chassis dimensions—430 x 300 x 185mm—and 19.5kg weight reflect its robust internal construction and premium transformer cores. This physical solidity contributes to resonance control and long-term durability. All wiring is hand-soldered, and the layout is optimised for minimal signal path length and electromagnetic interference.

Lyrebird EL84/4 Integrates Into Hi-Fi Systems with Ease and Transparency

Lyrebird EL84/4 Integrated Valve Amplifier is highly compatible with a wide range of source equipment and speakers. With an input sensitivity of just 0.7V for full output and a high 85kΩ input impedance, it accommodates both vintage and modern sources with ease. The wide frequency response—from 5Hz to 22kHz (-3dB)—ensures deep bass and extended highs, making it suitable for full-range speakers or detailed nearfield listening setups.
