TOPPING L30II NFCA Modules UHGF Technology 0.3uV Ultra Low Noise Cost-effective Headphone Amplifier (Silver)

 .
• .
• Improved NFCA: L30 II uses redesigned NFCA (Nested Feedback Composite Amplifier) module. It provides 2x output power at 300Ω load compared to L30. The new circuit has 0.3uV ultra low noise and 144dB dynamic range as well as 0.00006% THD+N.
• Sound quality is never a problem: With the help of NFCA, L30 II easily reach the top of the industry, and it has almost perfect performance regardless of distortion, dynamic range, and multi-tone testing.
• Three gain settings to suit different needs: L30 II has three gain options: -14dB, 0dB, 16.5dB. Improved gain settings can cover a wider range of needs to meet the needs of different headphones from low-sensitivity full-sized over-ears to high-sensitivity IEMs. With the help of extremely low noise 0.3uV, even IEMs will not hear any background noise.
• Best combo for active speakers: We also recommend that L30 II and E30 II be used with active speakers. Connect the two outputs of L3011 to headphones and active speakers. By switching the outputs of L3011, you can enjoy music on headphones and active speakers respectively.
• Low distortion while outputting high power: The L30 II can maintain ultra-low distortion output under high power load. Under 32 ohm load and 2500mW output, the THD+N is lower than 0.00008%; under 300 ohm load and 300mW output, the THD+N is lower than 0.00007%.
