The Topping A90 is the pinnacle of pure audio signal design in a headphone amplifier and speaker pre-amplifier.
The A90 comes equipped with NFCA modules (Nested Feedback Composite Amplifier), which along with ultra high-gain feedback technology provide excellent AC and DC performance. The high output current capability of the A90 allows it to drive low impedance headphones with ease. The combination of ultra-low noise and a high dynamic range of 145dB, drives the most sensitive IEMs without producing any audible noise or dark background.
The A90 features a 4-pin XLR, a 4.4mm Balanced, and a 6.35mm Single Ended output port. It also comes with the three-step gain setting and a wide variety of sensitivity settings that allow the amp to drive sensitive IEMs to power-demanding headphones.
