Fezz Audio Mira Ceti MK2 300B Single-Ended Valve Integrated Amplifier

Pure 300B Valve Sound, Refined for a New Generation

The Fezz Audio Mira Ceti MK2 is a beautifully engineered single-ended valve integrated amplifier, designed to capture the natural warmth, richness and musical expression that have made the legendary 300B triode one of the most revered valves in high-fidelity audio.

Building on the success of the original Mira Ceti, the MK2 introduces a redesigned circuit, upgraded signal path and carefully refined component selection. Combined with Fezz Audio's custom toroidal output transformers, these improvements deliver greater clarity, musical coherence and detail while preserving the unmistakable character of a traditional 300B amplifier.

With its elegant design, exceptional tonal qualities and modern valve management technology, the Mira Ceti MK2 offers a captivating listening experience for music lovers seeking a more intimate and emotionally engaging connection with their favourite recordings.

Legendary 300B Triode Performance

At the heart of the Mira Ceti MK2 are two directly heated 300B triode valves, operating in a pure Single-Ended configuration.

Renowned for their wonderfully expressive midrange, natural vocal reproduction and smooth, delicate high frequencies, 300B valves have long been associated with some of the most musically rewarding amplifier designs.

The Mira Ceti MK2 delivers 8 watts of output power, prioritising musical purity and tonal refinement over sheer power. When partnered with appropriately sensitive and compatible loudspeakers, it creates an exceptionally immersive soundstage, bringing voices and instruments to life with remarkable realism.

The amplifier is particularly well suited to jazz, acoustic, vocal and classical recordings, where its ability to communicate subtle textures, dynamic nuances and the natural character of instruments truly shines.

Custom Toroidal Output Transformers

A defining feature of the Mira Ceti MK2 is its use of custom-designed toroidal output transformers.

These transformers play a crucial role in the amplifier's performance, helping the 300B valves deliver a beautifully balanced presentation with impressive clarity, coherence and bass authority for a Single-Ended design.

The result is a sound that combines a rich, textured midrange with an open, delicate treble and a surprisingly confident low-frequency foundation.

Redesigned Circuit and Upgraded Signal Path

The MK2 benefits from significant internal improvements over its predecessor, including a redesigned amplifier circuit and optimised signal path.

Careful attention has been paid to component selection and circuit refinement, with the aim of preserving the smallest musical details while maintaining the natural flow and harmonic richness associated with valve amplification.

These enhancements help deliver a cleaner, more articulate and cohesive listening experience without sacrificing the warmth and musical character that make 300B amplifiers so appealing.

Automatic Bias and Advanced Valve Protection

Although the Mira Ceti MK2 embraces traditional valve amplification, its operation benefits from modern engineering.

The amplifier features an automatic bias control system, which continuously maintains the correct operating parameters of the valves. This eliminates the need for manual bias adjustments, making ownership more convenient and straightforward.

A delayed anode voltage activation system provides additional protection during startup, allowing the valves to warm up before the high voltage is applied. This helps reduce unnecessary stress on the valves and contributes to their long-term reliability.

Together, these features make the Mira Ceti MK2 a practical choice for enthusiasts who want the sonic benefits of traditional valve amplification without complicated maintenance procedures.

Flexible Connectivity and System Integration

The Mira Ceti MK2 features three RCA inputs for connecting traditional audio sources, such as CD players, DACs, streamers and phono stages.

An additional DIRECT input provides further integration possibilities, while dedicated 4Ω and 8Ω speaker connections allow the amplifier to be matched with a range of compatible loudspeakers.

Two extension board slots also provide scope for additional functionality through compatible expansion modules.

A More Personal Listening Experience

The Fezz Audio Mira Ceti MK2 is not designed simply to impress with power figures. Instead, it focuses on the qualities that make music genuinely enjoyable: natural tone, expressive vocals, instrumental texture and emotional involvement.

From the delicate resonance of an acoustic guitar to the subtle inflections in a singer's voice, the Mira Ceti MK2 presents music with an intimacy and authenticity that encourages long, relaxed listening sessions.

For enthusiasts looking to discover the distinctive character of 300B valve amplification, the Mira Ceti MK2 represents a compelling combination of traditional audio design, contemporary refinement and musical sophistication.
