The AK4490 DAC Chip:
The xDuoo XD10 Poke is utilizing a AK4490EQ DAC Chip of the company Akai Kasei Microdevices Corporation. The AK4490EQ is a new generation of premium 32-bit DAC, with 2-channels of AKM’s VELVET SOUND architecture that has been widely adopted by high-end audio companies like Astell&Kern, iBasoo, Fiio etc. This AKM4490EQ inside the xDuoo XD Poke supports native DSD, DXD and PCM signals, with sampling rates up to 32Bit / 384KHz for covering all mainstream audio formats.


Amplifier & Driving Power:
The xDuoo XD10 Poke is utilizing a OPA1662 (dual) series of bipolar-input operational amplifier, which achieves a low 3.3 nV/√Hz noise density with an ultralow distortion of 0.00006% at 1 kHz.
The OPA1662 op amps offer rail-to-rail output swing to within 600 mV with 2-kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30 mA.
The supported impedance of the xDuoo XD10 Poke is between 8 – 300 ohm with a rated output power of 250mW + 250mW @ 32ohm, which was able to drive most demanding In-Ear Monitors (final E5000), Earbuds (300ohm Samsara) and even power hungry headphones like the Sony SA3000 without difficulty.
