Fezz Audio - Luna Evo - EL34 Integrated Valve Amplifier

40 watts of EL34 warmth. Selectable Ultralinear and Triode modes. Modular expansion cards, subwoofer output, auto-bias, and a refined remote control. The Fezz Audio Luna is where tube tradition meets modern versatility — and music truly comes alive. Where Tradition Meets Innovation There is a quality to the sound of EL34 tubes that no solid-state circuit has ever fully replicated — a warmth, a dimensionality, a sense of musicians present in the room that draws you in and holds you there. The Fezz Audio Luna has been designed to deliver exactly that experience, while embracing the engineering advances that make a modern valve amplifier more versatile, more reliable, and more enjoyable to live with than ever before. Built on a foundation of four EL34 output tubes and three 12AX7 driver valves, the Luna delivers up to 40 watts in Ultralinear mode — with the full, dynamic presentation that makes EL34-based amplifiers so beloved by music lovers worldwide. Switch to Triode mode and the character shifts: power drops to 20 watts, and the sound becomes more intimate, more delicate, more alive to the finest nuances in the music. Two amplifiers in one chassis, each with its own distinct voice. The Luna is also a thoughtfully designed component for the modern listener. Modular expansion cards allow the platform to grow with your system. A subwoofer output enables seamless integration with a sub for extended low-frequency performance. Auto-bias eliminates the need for manual tube adjustment, keeping the amplifier optimally configured at all times. And a refined infrared remote control puts volume and input selection at your fingertips from the listening seat. This is Fezz Audio's philosophy made tangible: tradition and innovation in equal measure, united in service of the music. The Magic of EL34 The EL34 is one of the most celebrated output tubes in the history of valve amplification. Developed in the 1950s and refined ever since, it occupies a unique sonic territory — richer and more harmonically complex than the KT88, more refined and musical than the EL84, and with a midrange presence that brings vocals and instruments to life with an immediacy that is genuinely emotional. The Luna gives these legendary tubes the circuit they deserve: a Class AB topology with a wide frequency response of 16Hz to 115kHz, THD below 0.05% at full power, and output taps for both 4Ω and 8Ω speakers. Ultralinear & Triode — Two Amplifiers in One The ability to switch between Ultralinear and Triode modes transforms the Luna from a single amplifier into a genuinely versatile platform. Ultralinear mode — the factory default — harnesses the full 40-watt output of the EL34s, delivering a wide, dynamic, and authoritative presentation ideal for larger rooms and more demanding loudspeakers. Triode mode reduces output to 20 watts and reconfigures the circuit for a purer, more direct signal path — producing a sound that is more intimate, more harmonically rich, and more emotionally direct. The choice is yours, and it can be changed to suit the music, the mood, and the moment. Refined. Versatile. Ready for Your System. The Luna arrives fully equipped for the modern listening environment. Three RCA inputs plus a dedicated DIRECT input accommodate a wide range of sources. The subwoofer output enables integration with a powered sub for systems that demand extended bass performance. A tube cage is included for households where safety or aesthetics require it. And the auto-bias system ensures the EL34 output tubes remain perfectly set at all times — no multimeter, no manual adjustment, no expertise required. Feature Cards 🎛️ Selectable Ultralinear & Triode Modes Two distinct sonic personalities in a single chassis — 40 watts of dynamic, authoritative Ultralinear performance, or 20 watts of intimate, harmonically rich Triode sound. Switch between them to suit the music, the mood, and the moment. 🔧 Auto-Bias & Modular Expansion Automatic bias adjustment keeps the EL34 output tubes optimally configured at all times, with no manual intervention required. Modular expansion card slots allow the Luna to grow with your system and adapt to new requirements over time. 🔊 Subwoofer Output & HT Connectivity A dedicated subwoofer output enables seamless integration with a powered sub for extended bass performance. The DIRECT input supports home theatre bypass for flexible system integration. 📻 EL34 & 12AX7 Valve Complement Four EL34 output tubes deliver the legendary warmth, dimensionality, and midrange presence that has made this valve the benchmark of musical amplification for over seventy years — supported by three 12AX7 driver valves in a refined Class AB circuit.
