Product Summary
The Fezz Mira Ceti 300B MONO Tube Power Amplifier is a high-end monoblock valve amplifier designed to deliver the legendary sonic character of 300B triode tubes with exceptional musical realism. Hand-built in Poland, each amplifier operates as a dedicated mono power stage, with two units required for stereo playback.
Using a Parallel Single-Ended Class A design based around the iconic 300B vacuum tube, the Mira Ceti MONO produces rich harmonic detail, expansive soundstage depth and a beautifully natural midrange presentation. This topology is widely regarded as one of the most musically engaging amplifier designs available.
High-quality toroidal output transformers designed by Toroidy are used throughout the amplifier, helping provide excellent bandwidth and low noise while maintaining the purity of the single-ended signal path.
Designed to pair with a high-quality line preamplifier such as the Fezz Sagita series, the Mira Ceti 300B mono amplifiers provide impressive dynamics and control when partnered with efficient loudspeakers.
