XDUOO A35 ES9018K2M DAC & Tube Amplifier

The A35 is a high-end integrated tube amplifier meticulously developed by xDuoo for three years.Its preamp stage adopts one custom 12Ax7 and two 12AU7 tubes to build a long-tail phase-inverter amplifier circuit. The power stage features four EL34 tubes configured in a classic push-pull topology, de- livering a robust 45w output per channel. Built with an all-tube circuit design, every vacuum tube is strictly selected and precisely matched. Voltage Amplifier Stage Equipped with high-gain 12AX7 dual triode for initial signal amplification. It delivers excellent linearity and pure musical texture. Driver Stage Dual 12AU7 triodes feature low internal resistance, low noise and high current. It provides solid power and ample headroom. Power Amplifier Stage Four precisely matched EL34 tubes form a classic push-pull circuit.45W per channel output reproduces grand dynamics and delicate musical details. Ultra-linear Operation Mode Features ultra-linear amplification for outstanding dynamics and wide frequency response. It delivers solid bass, layered soundstage and clear, pleasant sound, performing well with all music genres. Multi-protection Circuits for Safe Listening Built-in relay protection with 60-second power-on delay to warm up tubes and eliminate switch-on pops. It automatically guards against overload and short circuits, protecting speakers and the unit.
