Integrated amplifiers — Fezz Audio Luna Evo

The Luna Evo is a tube integrated amplifier from Fezz Audio, built with an extraordinarily wide bandwidth and minimal output power. The Luna Evo brings Fezz Audio's considered tube-circuit engineering to a complete integrated chassis.

Key specs that matter

Three single-ended inputs are provided. Output power is a minimal 10W into 8 ohms. Frequency response spans an extraordinary 16Hz to 130,000Hz within plus-or-minus 3dB - a remarkable bandwidth extending far beyond conventional audible range. Signal-to-noise ratio is 84dB, with total harmonic distortion plus noise at 2.5% - a figure consistent with a genuine tube-based circuit topology, which some listeners specifically favour for the resulting harmonic character. At 285 x 220 x 417mm and 15kg, the Luna Evo's considerable weight relative to its modest output reflects serious output transformer and power-supply componentry.

Sound and use context

Expect the rich, harmonically engaging tonal character genuine tube-based circuit topology is broadly celebrated for, with the extraordinarily wide 16Hz-130kHz bandwidth combined with the modest 10W output demanding high-sensitivity loudspeakers.

Pairing

The modest 10W output demands high-sensitivity, high-efficiency loudspeakers to reach satisfying volumes.

Alternatives

Fezz Audio's own Fezz Mira Ceti 300B offers a related single-ended tube alternative within the same broader catalogue.
