The A900 is Topping's all new flagship Hifi Headphone Amplifier, born from their relentless pursuit of ultimate sound quality. Its refinement perfectly reflects their music focused philosophy.

The A900 is equipped with a full range of headphone outputs, providing up to six physical ports including 6.35, 4.4mm 4-pin XLR and dual 3-pin XLR and using premium connectors from Neutrik and Pentaconn. Customers can also configure these outputs as independent or simultaneous connection for personalised monitoring. The A900 also includes preamp outputs and offers a dedicated pure preamp mode. As a preamplifier, it matches the headphone amps performance, with THD+N <0.000055% making it an ideal companion for any power amplifier.

The A900 features a fully balanced relay based volume control system which reduces channel crosstalk to -153dB and with a precise 0.5dB stepped adjustment delivering a refined and comfortable control.

A 2-inch full colour display provides clear real time playback information. The knob not only offers precise control but also functions as a customisable function key.
