Topping L30 II Amplificateur casque NFCA Préamplificateur Argent

Improved NFCA

The Topping L30 II uses a revised NFCA (Nested Feedback Composite Amplifier) amplifier module. This one allows notably to double the output power available under 300Ω, compared to the L30. An output power offering the possibility to the L30 II to accompany the vast majority of headphones on the market, including the most demanding models with a high impedance. The new circuit also offers an ultra-low noise level measured at 0.3µV, a dynamic page of 144dB as well as a THD+N of 0.00006%.

Gain setting

In order to allow the L30 II to accompany both high-impedance headphones and very sensitive in-ear monitors, the amplifier offers a three-level gain control: -14dB, 0dB and 16.5dB.
