L30 II NFCA Headphone Amplifier Hi-Res Audio 560mW×2 L30II AMP (Black)

Improved NFCA: L30 II uses redesigned NFCA (Nested Feedback Composite Amplifier) module. It provides 2x output power at 3002 load compared to L30. The new circuit has 0.3 uV ultra low noise and 144dB dynamic range as well as 0.00006 % THD+N.. Compatible with almost all kinds of headphones: L30 II's output has high output voltage, high current, low output impedance, so no headphones that can't be dealt with. High output voltage can easily drive high impedance headphones. High output current allows low- sensitivity headphones to obtain enough power. The low output impedance will not bring unnecessary effect on FR when driving low-impedance headphones. Different headphones can be easily driven by the L30 II.. 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 %.. Three gain settings to suit different needs: L30 II has three gain options: -14dB, 0dB, 16.5 dB. 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-sensitity IEMs. With the help of extremely low noise 0.3 uV, even IEMs will not hear any background noise.
