Feature

●The new circuit shares the same 0.3uV ultra low noise and 145dB dynamic range and 0.0006% THD + N
●The L50 has three gain options. To meet the needs of low-sensitive full-size over-ear to high-sensitivity 1EM, you can just cover a wide gain range. With the help of very low noise of 0.3uV, even LEM will not hear background noise
●With the help of NFCA, the L50 is easily reached to the top of the industry and provides superior performance regardless of distortion, dynamic range or multi-tone testing
●When shutdown, the input signal will be output directly to RCA or TRS without amplifiing. This is suitable for working with active speaker/monitor speakers if your DAC has preamp function
●New NFCA circuits have been redesigned based on the same operating principle as the A30Pro. Provides twice the power of 300 ohms compared to L30
