TOPPING L50
Brand New NFCA circuit
Topping L50 characterizes redesigned new NFCA circuit based on the same working principle as that of A30 Pro. The new circuit provides 2x the power at 300 Ohm compared to L30, meaning it 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 reaches the top of the industry with ease, and the audio performance is perfect regardless of distortion, dynamic range, and multi-tone testing.
Wide Range of Adaptation to Headphone Impedance
L50 specializes in the high range of adaptation to headphone impedance. Once L50 meets the requirements of multiple ideal amps at the same time, it leads you to break the inertial thinking in the choice of amps: From now on, there is no need to choose amps based on the impedance of headphones. After that, all you need to do is choose Topping L50, and then pick up your favorite headphones, it can run them well.
Flexible Adjustment of Sensitivity
There are three gain options in Topping L50. It is sufficient to meet the needs of low-sensitivity full-sized over-ears to high-sensitivity IEMs when covering a wide gain range. With the help of extremely low noise 0.3uV, any background noise will not be heard.
Smooth Input
Topping L50 features smooth input. When shutting down,the input signal is directly output to RCA or TRS without amplification, which will be more suitable for working with active speakers/monitor speakers when the DAC has pre-amp function.
Designed to associate with E50
E50 is launched with ES9068AS sub-flagship chip, supporting PCM,DSD, MQA decoding. That is why L50 and E50 both have fully matched design languages and styles, and signals can transmit in balanced by TRS.
