Introducing the xDuoo XD-05 Basic2 DAC/Amp — Portable, Powerful, and Customizable: Now Available on Apos

[Apos Audio]

Hi all,

Here's the long-awaited successor to the Basic DAC/Amp from xDuoo. The XD-05 Basic2 DAC/Amp adds Bluetooth 5.4, swaps out the ESS DAC chip for a Cirrus Logic chip that offers slightly better specs, adds quite a bit of power (from 500mW to 750mW @32Ω), loses a bit of battery life, but—and this is exciting—adds op-amp swapping.

Product highlights 

• 750mW per channel output power
• Supports PCM 32bit/384kHz, DSD256, and MQA 8x
• Bluetooth 5.4 LE Audio with LC3, aptX, LDAC, and more
• 124dB SNR and THD+N as low as 0.0006%
• Runs on battery or DC power
• Replaceable op-amp chip
• High/low gain toggle
• Digital volume with 99-step precision
