About the SE84UFO25
The SE84UFO25 is a refined version of Decware's popular Zen Triode amplifier series, celebrating 25 years of design evolution. It is a single-ended Class A triode amplifier using one output tube per channel and a dual-triode input tube. The amplifier features Decware's proprietary Ultra Fidelity Output (UFO) transformers with frequency response beyond 80 kHz, providing exceptional imaging and resolution. It has a minimalist signal path with only two resistors and one capacitor, no negative feedback, and point-to-point wiring with no circuit boards. The 25th Anniversary model includes enhancements such as tube-regulated power supplies using OD3, OA3, and OC3 voltage regulator tubes, gold-plated switches and tube sockets, NOS Western Electric milliamp meters, and a choice of hardwood bases and knobs. It is hand-crafted in the USA with a lifetime warranty to the original owner. The amplifier delivers 2.3 watts RMS per channel or 6 watts in single-ended mono mode, with an input sensitivity of 2 volts and input impedance of 100,000 ohms. It is self-biasing and self-balancing, requiring minimal maintenance other than tube replacement every few years. The SE84UFO25 is praised for its ease of listening, midrange purity, temporal accuracy, and ability to reveal inner detail without warmth or harshness.
