Product Summary
The Fezz Lybra 300B Tube Amplifier is a high-end integrated valve amplifier designed for listeners who want the distinctive musical character of 300B tubes combined with greater drive and scale. Hand-built in Poland, the Lybra uses a parallel single-ended Class A design to deliver a rich, spacious and highly engaging presentation.
Using four 300B output tubes working in parallel pairs, supported by 6SN7 and 12AX7 driver valves, the Lybra delivers the tonal purity, expressive midrange and natural flow that 300B amplifiers are known for, while offering more power than a traditional single-ended 300B design.
High-quality toroidal transformers designed by Toroidy form the heart of the amplifier’s power and output stages, helping provide excellent bandwidth, low noise and stable operation. Automatic biasing also simplifies ownership and helps maintain consistent performance.
With its exposed tube layout, heavy steel chassis and distinctive Fezz styling, the Lybra 300B makes a striking centrepiece for a high-quality hi-fi system and is particularly well suited to partnering efficient loudspeakers.
