Sonic purity. The Topping A50s is a compact desktop headphone amplifier and pre-amplifier with exceptional sonic design and specifications. It brings all the clarity and detail you could want out of your favorite recordings. Pair it with the D50s DAC for a full, dynamic stack!
A50s uses the same NFCA (Nested Feedback Composite Amplifier) module from the flagship A90. Voltage Current hybrid feedback architecture along with UHGF (Ultra High Gain Feedback) technology provides excellent DC and AC performance. High output current drive capability allows the amp to drive low impedance headphones with ease. Ultra-low noise of 0.3uV is miles ahead of the competition, giving an absurdly high dynamic range of 144dB and no audible noise and darkest background for the most sensitive IEMs.
6.35mm SE & 4.4mm balanced output
Although there is only a single-ended input, A50s has a built-in balanced amp circuit. Therefore, it can drive single-ended headphones via the 6.35mm output, and drive balanced headphones with the 4.4mm balanced output.
