TOPPING DX1: The Essential Desktop Hi-Fi Upgrade (No Power Adapter Needed)
The TOPPING DX1 is the ultimate entry-level all-in-one solution for your desktop audio needs. Combining a high-performance DAC and a capable headphone amplifier in a compact chassis, the DX1 is plug-and-play simplicity. It requires no external power adapter, running entirely on USB power, making it the cleanest and easiest way to upgrade the sound quality of your PC, laptop, or game console.
New-Generation AKM Chipset for Pristine Sound
The DX1 utilizes modern components to deliver metrics far surpassing its budget price point.
AKM AK4493S Velvet Sound Chip
The DX1 is built around the new-generation AKM AK4493S DAC chip, part of AKM’s acclaimed Velvet Sound technology. This 32-bit DAC delivers superb decoding capabilities with an impressive Signal-to-Noise Ratio (SNR) of 120dB and ultra-low Total Harmonic Distortion plus Noise (THD+N) of less than 0.0002%.
XMOS XU208 and Hi-Res Support
Equipped with the XMOS XU208 USB receiver, the DX1 ensures stable and reliable signal processing. It supports high-resolution playback up to 32bit/384kHz PCM and native DSD256, providing an authentic high-resolution audio experience for your desktop.
Power and Simplicity in a Compact Form
The DX1 is engineered for maximum convenience and compatibility without sacrificing drive capability.
Powerful Headphone Output and Dual Gain
Despite its small size, the headphone amplifier delivers up to 280mW of power per channel into a $32\Omega$ load. It features two gain settings (Low and High), ensuring it can handle both sensitive In-Ear Monitors (IEMs) and most full-sized headphones.
Discrete LNRD Circuit for Ultra-Low Noise
The DX1 employs a Discrete Low Noise Reference Driver (LNRD) circuit, which effectively suppresses noise and interference coming from the USB power source. This results in an incredibly low noise floor, ensuring a "dark background" even with highly sensitive headphones.
Seamless Plug & Play Integration
-
Direct USB Power: The DX1 is fully powered by its USB input, eliminating cable clutter and the need for a wall adapter.
-
Dual Headphone Jacks: Features both 6.35mm and 3.5mm headphone outputs on the front panel, allowing for universal compatibility.
-
Fixed-Level RCA Output: Includes a stereo RCA line out with a fixed output level, allowing it to function as a pure DAC to feed a separate, more powerful amplifier if desired.
