TOPPING DX1
New-Generation AKM DAC Chip
Topping has equipped the latest DX1 with the latest generation AKM DAC chipset. It houses the AK4493S DAC chip from AKM’s Velvet Sound technology, it’s a 32-bit DAC upgraded from the classic AK4493. It helps the DX1 to provide crisp high-resolution audio signal decoding.
High-Resolution Audio Decoding
Topping DX1 is an all-in-one solution for all your Hi-Fi needs. The device supports high-resolution PCM and DSD signal decoding bringing an authentic high-resolution audio experience to your desktop. It has an XMOS XU208 USB receiver chip that provides 32-Bit/384kHz and Native DSD256 signals.
Plug & Play, No Adapter Required
Topping DX1 is widely compatible with a range of desktop devices. It doesn’t require any additional power adapter and works directly off your sources like Windows/Ma/Linux and even Android devices.
Discrete LNRD Circuit
In order to reduce noise from USB power, DX1 features a Discrete LNRD circuit(low noise reference driver). It filters out the noise and interference of USB 5V power and provides a clean and stable power supply to the device.
Compact Size, Powerful Output
Topping DX1 is a powerful device, it packs a punch in its compact size. It has a powerful output rating of up to 280mW @ 32Ω of load. It has two level gain modes, Low and High. Easily power your IEMs and HPs with the DX1.
