Unboxing and Review: Topping D900 - Flagship DAC/Preamp with Hi-Res File Support (2025)

Prepare to be blown away by the latest innovation in audio technology: a DAC/preamp that promises to redefine sonic excellence for under £2000. But here's where it gets controversial: can a single device truly marry flagship performance with affordability? Topping, the British brand that previously wowed us with the DX5 II—a budget DAC offering premium features at a fraction of the cost—is back with a new contender. Enter the D900, their flagship model, which seamlessly blends DAC functionality with preamplification to deliver "exceptional value for both hi-fi enthusiasts and headphone aficionados." And this is the part most people miss: it’s not just about the specs; it’s about the experience. Topping’s proprietary 'PSRM' conversion technology takes center stage, promising to convert digital audio signals with unparalleled accuracy. By minimizing power supply interference and using meticulously selected components, the D900 aims to achieve crystal-clear audio with minimal noise—a bold claim that’s sure to spark debate among audiophiles. Connectivity is where this device truly shines, offering a whopping eight digital inputs, including USB, coaxial, optical, AXLR, and even HDMI. On the analog side, balanced twin XLR outputs ensure compatibility with high-end systems. But here’s the kicker: the D900 also supports hi-res Bluetooth, including LDAC and aptX Adaptive for 24-bit/96kHz streaming, as well as aptX HD for 24-bit/48kHz streams. This level of versatility is rare, even in devices twice the price. Design-wise, the D900 is a sleek powerhouse, measuring just 33 x 5.7 x 21cm. Its aluminum chassis, complete with heatsinks and vibration-absorbing pads, is engineered to eliminate sonic interference and unwanted resonance—a detail often overlooked but crucial for pristine sound. The included aluminum remote and on-unit color screen, featuring touch-sensitive buttons and a programmable rotary control, add a layer of convenience that’s both intuitive and luxurious. At £1799, the Topping D900 is available now, but the question remains: does it live up to the hype? Here’s a thought-provoking question for you: In a world where audio gear often prioritizes either performance or affordability, can the D900 truly deliver the best of both worlds? Let us know your thoughts in the comments—we’re eager to hear if you think this device is a game-changer or just another contender in a crowded market.
