Portable Tube DAC Amp with JAN6418 Vacuum Tube, 460mW/480mW Balanced Output, USB C Dongle DAC for IEMs & Headphones, Amplifier for Phone/PC/Mac

JAN6418 Military-grade Vacuum Tube Most portable DACs rely on solid-state chips that can sound cold and clinical. The M3 Ultra uses a genuine JAN6418 vacuum tube a military-spec component that delivers rich harmonics, smooth mids, and natural decay. Vocals feel more intimate, guitars have body, and fatigue melts away after hours of listening. You get 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 solves this with a patented triple noise reduction system: circuitlevel balanced design, algorithmic microphonics cancellation, and physical shock absorption. The result? Deadquiet performance whether its dangling from your phone in your pocket or sitting on your desk.
460mW / 480mW Balanced Output Dont let its tiny size fool you. The M3 Ultra delivers 460mW (3.5mm) and 480mW (4.4mm balanced) of clean power. That means it can handle everything from ultrasensitive IEMs to demanding planar magnetic headphones. Whether youre using multiBA IEMs on a crowded subway or HD 600s at your desk, youll have more than enough headroom.
Ultralow Distortion Tube sound often comes with high distortion. Not here. The M3 Ultra keeps THD+N as low as 0.0003% (4.4mm) while preserving the tubes musical character.
