A50S Features: Ultra-High Performance A50s uses the same NFCA (Nested Feedback Composite Amplifier) module? from 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 driving 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 by 6.35mm output, and drive balanced headphones by 4.4mm balanced output. An excellent preamp The NFCA modules of A50s are not only able to drive the headphones but also apply to be a preamplifier with the same?ultra-high performance. When it is in preamp mode, output impedance is as low as 20ohm, which is widely suitable for various?devices. ?
