Topping L30 II, Topping L30 new version

The Topping L30 II is the evolution of the L30. This new version retakes the base of the architecture of the previous model, but with many improvements aimed at optimizing the performance of the device as well as its sound reproduction.

One of the novelties of this device is the incorporation of an improved NFCA module and a power delivery of 2 x 560mW compared to the 280mW of the L30.

NFCA amplifier module

L30 II uses redesigned NFCA module. It provides 2x output power at 300 Ohms load compared to L30. The new circuit has a 0.3uV ultra low noise and 144dB dynamic range as well as 0.00006% THD+N.

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 0.0008%; under 300 ohm load and 300mW output, the THD+N is lower 0.00007%.

L30II has three gain options: -14dB, 0dB, 16.5dB. Improved gain settings can cover a wider range of needs to meet 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.
