JAN6418 Military-grade Vacuum Tube Most portable DACs rely on solid-state chips that can sound cool and analytical. The M3 Ultra employs an authentic JAN6418 vacuum tube a military-spec component that provides rich harmonics, smooth mids, and natural decay. Vocals feel more intimate, guitars have body, and fatigue fades away after extended listening. You achieve that sought-after "tube warmth" without the desktop footprint. Triple Noise Reduction Vacuum tubes are sensitive to vibration, which can cause microphonics that annoying ringing sound when you touch or move the DAC. M3 Ultra addresses this with a patented triple noise reduction system: circuit-level balanced design, algorithmic microphonics cancellation, and physical shock absorption. The outcome? Silent performance whether its dangling from your phone in your pocket or resting on your desk. 460mW / 480mW Balanced Output Do not let its compact size deceive you. The M3 Ultra delivers 460mW ( 3.5 mm) and 480mW ( 4.4 mm balanced) of clean power. This means it can drive everything from ultra-sensitive IEMs to demanding planar magnetic headphones. Whether youre using multi-BA IEMs on a crowded subway or HD 600s at your desk, youll have ample headroom. Ultra-low Distortion Tube sound often comes with high distortion. Not here. The M3 Ultra maintains THD+N as low as 0.0003 % ( 4.4 mm) while preserving the tubes musical character. You get the best of both worlds: the rich, organic texture of analog along with the low-distortion clarity of high-end solid-state design.
