Fezz Audio Lybra

Unlike many tube amplifiers that lean into a warm, colored sound, the Lybra 300B is designed for neutrality and speed. It offers the harmonic richness of 300B tubes while maintaining the tight bass control and transparency more commonly associated with high-end solid-state gear.

With 15 watts per channel in a Parallel-Single-Ended Class-A configuration, this amplifier performs best with speakers of moderate to high sensitivity, typically 90dB or higher. It is designed to drive these speakers with exceptional articulation and authority rather than sheer brute force.

The primary difference between the two versions is the aesthetic design and chassis construction. Both versions share the same internal circuitry and performance characteristics, allowing you to choose the look that best fits your home audio setup.

The Lybra 300B features an auto-bias circuit, which simplifies tube maintenance and ensures consistent performance without the need for manual adjustments. This makes it a more user-friendly entry into the world of high-end tube amplification.

The standard unit features three analog RCA inputs for your traditional sources. However, Fezz Audio offers an optional Bluetooth aptX 5.0 module if you require wireless connectivity for streaming from mobile devices or computers.

The included tube cage is designed to protect the glass tubes from accidental damage and prevent direct contact with hot surfaces. While it can be removed for a more open aesthetic, we recommend keeping it installed if you have pets or small children in the home.
