Description
- The Gen5 NuTube 6P1 technology in the Cayin C9ii offers adjustable tube sound with high and low voltage settings, allowing users to customize the sound signature.
- The Dual Tube Sound system provides two modes: Classic mode delivers a rich, warm tube sound, while Modern mode offers a cleaner and more detailed sound with less distortion.
- The Anode Modes further refine the tube sound, with the ability to shift between a deep, rich tube sound or a more balanced, minimal tube effect depending on your preference.
- In Solid-State Mode, the amplifier provides a neutral and balanced sound without any tube coloration, appealing to listeners who prefer a pure, unaltered sound signature.
- The amplifier features a fully symmetric design, ensuring high-quality and clear amplification through its three-stage circuit, enhancing the overall audio performance.
- The Negative Feedback (NFB) system allows users to switch between two audio experiences: when NFB is on, the sound becomes more spacious and detailed, and when it is off, the sound is fuller and richer with a stronger bass presence.
- Finally, the Cayin C9ii supports multiple amplifier modes, including Class A/AB, single-ended, and balanced inputs and outputs, giving flexibility in how the amplifier is used.
