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.
