Despite its deceptively compact size, this is more powerful than it looks. The OPA1622 operational amp is able to push currents of up to 140mA, making it suitable for a large selection of earphones and headphones.
Sound Comes First
No Annoying Interference and Noise
The low-pass filter in the Texas Instruments OPA1662 helps eliminate distortion and signal noise, which promotes the signal-to-noise ratio to an excellent value of 112dB.
Amped Up for Amazing Audio
The power in the internals of the XD-10 gets pushed to a highly efficient power conversion circuit. Despite the power efficiency, the dynamic range of the output is greatly increased, resulting in energetic bass and dynamic audio for all your purposes.
The AKM AK4490 is a flagship-grade DAC, with a quality that befits the type of product we are trying to develop for you. The chip supports decoding of DSD (with a native rate of 32-bit/384kHz), DXD, and PCM signals. No matter the audio format, this piece of equipment can play it.
Octacore Processing Chip
The xDuoo XD-10 utilizes the octacore processing chip called the XS1-U8A-64 for its asynchronous transfer mode. This chip has quite the resume, with support for WASAPI, ASIO, and KS kernel stream mode. PCM audio goes as high as 32-bit at 384kHz, support is up to DSD 256 (with DoP Native mode), and DXD audio can be decoded up to 32-bit at 352.8kHz. All you need to know is that this is a beast of a processor.
Twin Crystal Oscillators
The clock source here is a pair of ultra-low phase noise crystal oscillators, capable of running separately at 44.1K and 48K frequencies. The system ensures switching between these frequencies to make certain that there’s no interference between them.
Volume Control Chip
A professional-grade volume control chip from Texas Instruments, the PGA2311, is used for its precise performance. There will be no worries about distortion, with a THD that is less than 0.0001%.
Intelligent Energy Optimization
The XD-10 is able to detect when equipment is connect to the jack. This enables it to save power when nothing is inserted, to give you as much as three times the power out of a single charge.
