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.
