Amplifier L30 II High-Resolution Audio Earphone AMP

Improved Amplifier Module: The L30 II features a redesigned NFCA (Nested Feedback Composite Amplifier) system. It supplies twice the output at 300Ω resistance compared to the earlier L30. The new system exhibits an extremely low noise of 0.3uV, a range of 144dB, and 0.00006% THD+N. Compatible with almost most kinds of headphones: The L30 II’s output includes elevated voltage, minimal impedance, making it capable for any headphones. The high output voltage can effortlessly handle high impedance headphones, while the high current allows low-sensitivity headphones to receive sufficient power. The low impedance guarantees there’s no unwanted effect on FR when powering low-impedance headphones. Low distortion at high power: The L30 II retains ultra-low distortion while at high power. With a 32Ω load and 2500mW performance, the THD+N is less than 0.00008%; with a 300Ω resistance and 300mW output, the THD+N is lower than 0.00007%. Three adjustment settings for varied needs: The L30 II features three gain modes: -14dB, 0dB, 16.5dB. Enhanced gain controls accommodate a wider range of needs to suit different headphones from low-sensitivity full-sized over-ears to high-sensitivity IEMs. With the 0.3uV extremely low noise, advanced IEMs will not hear any background noise.
