It's always exciting when a new piece of gear catches our attention, and the Fezz Olympia EVO Integrated Amplifier is no exception. Hailing from Poland, Fezz Audio has unveiled an amplifier that seems to merge the warmth of classic tube sound with modern versatility, making it a noteworthy addition to the audiophile landscape.
The Olympia EVO Integrated Amplifier delivers a robust 100 watts per channel in a dual-mono configuration, powered by eight KT88 vacuum tubes. This setup promises a dynamic and immersive audio experience, harnessing the rich tonal qualities that tubes are celebrated for. Complementing the KT88s are two 12AX7 and two 12AU7 tubes, rounding out the amplifier's tube array for nuanced sound reproduction.
One of the amplifier's standout features is its user-friendly design. Equipped with a remote control, it offers the convenience that modern listeners appreciate. The inclusion of a standby mode and a 2-minute pre-heating cycle not only enhances performance but also extends the longevity of the tubes—a thoughtful touch for those who value durability.
Fezz Audio has also incorporated a modular expansion slot into the Olympia EVO, allowing for future upgrades like a Bluetooth adapter, DAC, or phono stage. This adaptability ensures that the amplifier can evolve alongside your system, accommodating new technologies and preferences without necessitating a complete overhaul.
On the technical front, the amplifier provides three RCA line inputs and a power amplifier input, supporting both 4-ohm and 8-ohm speakers. Its frequency response ranges from 16 Hz to 80 kHz, capturing a wide spectrum of audio frequencies with fidelity. With a total harmonic distortion of less than 0.1% below 100 watts and less than 1% at full power, the Olympia EVO emphasizes clean and accurate sound reproduction.
Additional specifications include a damping factor greater than 30, an input impedance of 50 kΩ, and a sensitivity of 0.7 V. Power consumption is rated at 350 W when idle and 700 W at full power, reflecting its substantial performance capabilities.
The Fezz Olympia EVO Integrated Amplifier is already available for purchase, with a recommended retail price of 23,900 zloty (approximately £5,495). For those seeking an amplifier that blends traditional tube aesthetics with modern functionality, it presents a compelling option that's both versatile and future-proof.
