The Fezz Luna Mini EVO is a compact valve integrated amplifier running single-ended in class A, from Fezz Audio, the Polish manufacturer based in Juchnowiec Koscielny. It was announced together with the larger Luna EVO, went on sale in November 2025 at a UK price of GBP 1,695, and together the two take over from the older Alfa Lupi and Silver Luna. Fezz lists it at PLN 6,500 in Poland, and the two finishes on offer are Black Ice and Moonlight.
Key specs that matter
Output is 2 x 10 W, delivered from separate 4 ohm and 8 ohm speaker taps, covering loudspeaker loads between 4 and 8 ohm. The chassis is described by Fezz as compact in size. Signal bandwidth runs from 16 Hz to 130 kHz, S/N reaches 84 dB, while THD remains under 2.5 percent at 1 kHz and full power. Connections comprise three RCA line inputs plus a sub-out. Power consumption is 100 W, the net weight is 15 kg, and the case measures 285 mm wide, 417 mm deep including terminals and knobs, and 220 mm tall with the valve cage mounted.
Engineering and use context
One EL34 pentode per channel handles the output, working single-ended in class A, while a 12AX7 double triode in each channel acts as the driver, giving four valves in all. Bias is adjusted automatically, and the feature list includes a dedicated valve pre-heating mode. A signal ground switch sits among the connections for dealing with hum. An expansion slot accepts optional add-on boards - Fezz lists DAC, phono, XLR, RCA and Bluetooth modules - so digital sources, a turntable or wireless playback can be added later without a separate box. Fezz groups the sub-out, an infrared remote handset and a protective valve cage under options included with every unit, so none of them costs extra.
Pairing
Fezz aims the modest output at efficient bookshelf or floorstanding loudspeakers, and it is meant for owners who want a valve integrated amplifier in a smaller chassis than the Luna EVO. The sub-out is the route for adding a powered subwoofer. Without the phono module, vinyl playback calls for a standalone phono preamplifier, and without the DAC module, a streamer or CD player has to feed one of the analogue RCA inputs.
Alternatives
The Fezz Titania MK2 is the larger integrated valve amplifier Fezz currently offers - it runs in class AB with four KT88 and three 12AX7 rated at 60 W, with an 85 dB signal-to-noise ratio and two expansion slots.
