The Topping DX9 is the manufacturer's 15th anniversary commemorative model and its most powerful all-in-one device to date, using the AK4499EQ DAC chip. The proprietary high-performance discrete amplifier circuitry contains 6 independent modules, so the single-ended/balanced amplifiers are completely independent and do not interfere with each other. Each module contains 39 transistors, which achieve excellent performance through precise alignment, outperforming various similar products on the market. The amazing drive power of 7000mW x 2 @32Ω is sufficient to drive all kinds of headphones. The colorful dual screens are equipped with Topping's new Aurora UI, settings can be quickly customised. The 8-channel digital input can be connected to multiple front-end audio sources simultaneously. Independent line outputs and preamp outputs can operate simultaneously, providing multiple uses in a single device. The DX9 is a well-deserved home music centre for any avid music lover.
