Product Summary
The Fezz OVO is a premium valve headphone amplifier designed for listeners who want the intimacy, warmth and immediacy of a single-ended tube design. Working in pure Class A triode configuration, it brings Fezz’s valve amplifier character to personal listening, giving headphones a rich, spacious and highly involving sound.
Using EL84 output valves and a 12AX7 input valve, the OVO is built to drive a wide range of headphones with confidence. Switchable impedance settings make it easier to match different headphones, from easier portable models through to more demanding high-end designs, while balanced and unbalanced headphone outputs give useful connection flexibility.
