Topping A90 Discrete Headphone Amplifier Pre-Amplifier Relay Volume Control Precise and Matched (A90D Black)
►Fully discrete NFCA also create wonderful amp► TOPPING A90D uses fully discrete components to redesign the NFCA (Nested Feedback Composite Amplifier)module. 4 built-in NFCA-Discrete modules which each them uses 39 transistors build up fully balanced structure. The optimized Voltage Current hybrid feedback architecture along with UHGF (Ultra High Gain Feedback) technology provide excellent DC and AC performance. ►High output voltage, high current, low output impedance, no headphones that can't be dealt with►High output voltage can easily drive high impedance headphones; High output current allows low-sensitivity headphones to obtain enough power; The low output impedance
