Along with the latest E50 MQA desktop DAC, Topping has unveiled its latest balanced headphone amplifier, Behold the latest Topping L50. Using a redesigned NFCA circuit, the L50 brings extraordinary clean sound signal amplification with ultra-low distortion and high SNR ratings. The amplifier has a maximum output power rating of up to 3500mW or 3.5W at 16Ω of load. Even at 600Ω, the L50 provides up to 290mW of power that is more than enough to power up demanding cans without any trouble. For sensitive IEMs, don’t worry, the Topping L50 has an ultra-low output impedance of <0.1Ω and a super clean noise-floor, pair them without worrying about any background noise. The latest Topping L50 is designed to match with the latest E50 MQA DAC, making an amazing Desktop stack with MQA decoding and powerful output.

Redesigned new NFCA circuit based on the same working principle as the one in A30 Pro. It provides 2x power at 300 Ohm compared to L30.
The new circuit shares the same 0.3uV ultra-low noise and 145dB dynamic range as well as 0.00006% THD+N.

With the help of NFCA, L50 easily reaches the top of the industry, and it has almost perfect performance regardless of distortion, dynamic range, and multi-tone testing.

L50 has three gain options. Covering a wide gain range is sufficient to meet the needs of low-sensitivity full-sized over-ears to high-sensitivity 1EMs. With the help of extremely low noise 0.3uV, even lEMs will not hear any background noise.
