Fezz Audio describes the Omega Lupi as a highly neutral amplifier that combines a natural, fluid presentation with a solid bass foundation. Its ability to accommodate a broad range of headphone impedances makes it an exceptionally versatile partner for both demanding high-end headphones and more conventional models.

At the heart of the Omega Lupi Evolution is a push-pull Class AB1 vacuum tube circuit using four PCL86 tubes with automatic bias. The design delivers up to 2 × 250mW of output power, providing ample drive for headphones across its 32–600 ohm operating range. The wide 20Hz–120kHz (-3dB) frequency response allows the amplifier to preserve the detail and character of high-quality recordings while maintaining the distinctive musicality of a well-designed tube circuit.

The result is a presentation with natural instrumental timbre, precise imaging and a satisfying sense of depth. Vocals and instruments take on convincing body and presence, while the solid bass foundation provides music with weight and authority. Whether you’re listening to intimate acoustic recordings, vocals, jazz, classical music or complex modern productions, the Omega Lupi Evolution is designed to let your headphones reveal what they are capable of.

The Omega Lupi Evolution is also a striking piece of audio equipment. Its distinctive Fezz Audio design places the vacuum tubes prominently on top of the chassis, creating a visual centerpiece for a dedicated headphone system. The included protective tube cage provides an added level of protection while maintaining the amplifier’s distinctive appearance, and the remote control adds convenient control from your listening position.
