Feature(may vary by option.)
●👍 Improved NFCA ▶️TOPPING 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.
●👍 Compatible with almost all kinds of headphones ▶️ L30 IIs output has high output voltage,high current,low output impedance,so no headphones that cant 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.
●👍 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 L30II and E30II be used with active speakers. Connect the two outputs of L30II to headphones and active speakers. By switching the outputs of L30II, you can enjoy music on headphones and active speakers respectively

Description
TOPPING L30II - linear headphone amplifier & Pre-amplifier
TOPPING L30 II is a high-performance linear headphone amplifier that supports RCA input and output,equipped with a 6.35mm headphone jack and gain selections function.
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.
Low distortion while outputting high power
The L30II 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 ll 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.
