Topping Audio A50s Hi-Fi forforstærker til hovedtelefoner

With the A50s, Topping offers a high quality headphone amplifier and sedentary preamplifier combo, integrating both balanced and unbalanced connections. Its optimized circuits, based on very good audio components, allow a precise, detailed and musical restitution. The A50s is also designed to be versatile, capable of adapting to the vast majority of headphones and earphones on the market, including demanding models. At the heart of the A50s is an NFCA (Nested Feedback Composite Amplifier) module, identical to the one used in the brand's flagship, the A90. Its hybrid current/voltage architecture associated with UHGF (Ultra High Gain Feedback) technology offers excellent DC and AC performance. A high output current allows the amplifier to accompany all types of headphones. An ultra-low noise level of 0.3µV, a dynamic range of 144dB and the absence of background noise also allow the A50s to easily power the most sensitive EMIs.
