Topping L50

The Topping L50 is a desktop headphone amplifier with an architecture optimized for incredible audio performance. It is equipped with a new generation NFCA (Nested Feedback Composite Amplifier) circuit. The L50 is highly versatile, with robust power reserves and offers gain control to adapt to all types of headphones. The NFCA circuit of the L50 allows it to develop significant power, delivering twice the output power. This design achieves an extremely low noise floor of only 0.3μV, a dynamic range of 145dB and a THD+N (Total Harmonic Distortion plus Noise) of 0.00006%. The Topping L50 is equipped with single and balanced connectors to adapt to a variety of listening equipment. It provides single RCA and balanced 6.35mm TRS connectors as inputs. Similarly, the output includes a balanced 4-pin XLR and a single 6.35mm connector. It is important to note that, when the L50 is turned off, the input signal is routed directly to the RCA and TRS outputs without amplification, allowing it to work flawlessly with active speakers, provided the DAC has a preamplifier function.
