With 4.4mm balanced and 6.35mm headphone outputs, adjustable gain, pre-out functionality, and a compact aluminum chassis with transparent acrylic panels, it suits a wide range of headphones and systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHybrid Tube-Transistor Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MT02 uses a hybrid amplifier topology that pairs dual 6J1 tubes in the voltage gain stage with a transistor-based Class-A output stage. This delivers the smooth tonal character and rich midrange of vacuum tubes while providing the current delivery and control needed to drive demanding headphones.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual 6J1 Vacuum Tube Stage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTwo 6J1 vacuum tubes work in the preamplification stage, contributing warmth, natural vocals, and smooth high frequencies. The tube stage preserves musical detail while creating a relaxed, fatigue-free listening character that complements both modern and classic recordings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClass-A Output Power\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe transistor-based Class-A amplification stage delivers up to 1,500mW into a 32Ω load, powering everything from efficient portable headphones to higher-impedance designs. High current delivery, fast transient response, and controlled bass maintain clarity across dynamic passages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBalanced \u0026amp; Single-Ended Outputs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFront-panel 4.4mm balanced and 6.35mm single-ended headphone outputs provide compatibility with today’s most common headphone connections. A selectable high and low gain switch makes it easier to match output levels with different headphone sensitivities.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePre-Out for System Integration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe integrated pre-out lets the MT02 function as a tube preamplifier for external amplifiers or powered speakers. Volume stays synchronized through the front-panel control, making it easy to integrate into a desktop or two-channel listening system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePremium Components \u0026amp; Protection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eELNA audio coupling capacitors and Rubycon filter capacitors support low noise and stable performance. An intelligent relay protection system introduces a 30-second startup delay for tube warm-up, minimizes power-on\/off pop noise, and provides overload and short-circuit protection for both the amplifier and connected headphones.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier
