Topping A90 Discrete Headphone Amplifier
The A90 Goes High Performance
The Topping A90D is a discrete headphone amplifier that delivers a clean, high-headroom approach to desktop amplification. The original A90 already brought a host of high-end features to the table with impressive, low-noise performance—and now, the “D” version of this classic amp comes with Topping’s rock-solid Discrete Nested Feedback Composite technology. That amounts to an improvement in total harmonic distortion and an impressive increase in output power for a richer, less-distorted experience. Under the hood, you’ll find a new ground loop noise terminator, 12-volt trigger interface, a 145-decibel dynamic range, and a host of I/O capabilities including 4-pin XLR and 4.4-millimeter balanced outputs as well as commensurate inputs on the front end—offering the ultimate engine to drive even your most finicky pair of headphones or IEMs.
