Back and better than ever 

The second generation of the TOPPING L30 amplifier is here. With a totally redesigned NFCA amplifier, the L30 II makes significant improvements over its predecessor: better THD+N level, better dynamic range, double the output power, wider gain spread, and increased output voltage.

Compatible with all kinds of headphones

With high output voltage, high current, and low output impedance, the L30 II can power any kind of headphone. It easily drives power-hungry planar magnetics, highly-sensitive IEMs, and everything in between.

High power, low distortion

The L30 II manages ultra-low distortion beneath a high power load. For example, under a 32Ω load and 2500mW of output, the THD+N is lower than 0.00008%; under a 300Ω load and 300mW of output, the THD+N is lower than 0.00007%. 

Three gain settings

With three gain options from -14dB to 16.5dB, the L30 II can cover a wider range of needs for different headphones than the original model.
