iBasso Audio AMP16 Dual Raytheon JAN6418 Balanced/Single-Ended Tube Amplifier Card

Key Features:

  • Dual Raytheon JAN6418 Tubes: Military-grade pentode tubes with a 22.5V anode voltage, delivering a rich, analog sound with a Cold War-era legacy.
  • TUBE + Class AB Dual Modes: Switch between vintage tube warmth and pristine transistor clarity for versatile listening.
  • Powerful Output: 2000mW + 2000mW @ 32Ω (12V DC-IN) via 4.4mm balanced output, driving any headphone with ease.
  • Luxurious Circuitry: Features dual tubes, four TI op-amps, and four BUF634A buffers for exceptional sound refinement.
  • JRC Volume Control: 100-step hardware adjustment suppresses noise and enhances precision.
  • Hand-Matched Tubes: Each pair undergoes rigorous testing in an APx555 analyzer for unmatched audio quality.

Technology and Innovations:

The iBasso Audio AMP16 is a revolutionary amplifier card exclusive to the DX340 player, merging the soulful glow of vacuum tubes with modern solid-state precision. Powered by two Raytheon JAN6418 tubes—relics of North American military labs—it awakens their potential with a 22.5V anode voltage, infusing music with a timeless metallic resolve. Dual TUBE and Class AB modes offer a sonic multiverse: TUBE mode recalls the 1950s golden age with warm, misty harmonics, while Class AB unleashes transistor-driven clarity free of noise or interference. Its lavish design includes four TI op-amps and four BUF634A buffers, forming an eightfold sonic oracle that refines audio into a celestial masterpiece. With 2000mW per channel and support for 12V DC-IN, the AMP16 conquers even the most demanding headphones, while the JRC hardware volume control tames noise with 100-step precision. Every tube pair is hand-matched using an APx555 analyzer, ensuring harmonic distortion remains imperceptible.
