Fully discrete NFCA also create wonderful amp
As its name, A90 Discrete uses fully discrete components toredesign the NFCA (Nested Feedback Composite Amplifier)module. 4 built-in NFCA-Discrete modules which each themuses 39 transistors build up fully balanced structure.Theoptimized Voltage Current hybrid feedback architecturealong with UHGF (Ultra High Gain Feedback) technologyprovide excellent DC and AC performance. Benefiting fromthe new design, the output capability is stronger than ever,which allows the amp driving low impedance headphoneseven more effortlessly. The paralleled ultra low noiseprecision matched transistors in the design ensured theunparalleled distortion and noise performance.
