In recent times we’ve seen the dongle DAC market explode with new models coming out almost every week. But there hasn’t been near as much in the way of affordable entry-level desktop DACs. Now, the xDuoo MU-601 is here to fill the gap. The MU-601 is a proper 32-bit/384kHz DAC and is just $129.
So what kind of performance can you get for such a low price? Well, there’s a lot to like about the MU-601: for starters, it comes with an ESS ES9018K2M DAC chip, dual high-precision active crystal oscillators and high-quality XMOS XU208 USB receiver chip.

But maybe the best thing about this DAC is how great it looks. The chassis is a mix of the same great sand-blasted aluminium body we saw on the MT-602 and MT-604 models plus a full-front glass panel that gives it a really sleek and modern aesthetic.
The ES9018K2M SABRE Reference DAC chip uses the Hyperstream II DAC architecture and Time Domain Jitter Eliminator to deliver uncompromising audiophile-grade audio. Furthermore, the asynchronous transmission from the XMOS XU208 USB receiver chip greatly reduces jitter.

The MU-601 uses its own DC 12V independent power supply that greatly reduces any electrical interference compared to using your computer’s noisy USB power. This DAC would be a great match for the xDuoo MT-602 tube amplifier.
The xDuoo MU-601 DAC is available now from Apos Audio and comes with their excellent 2-year extended warranty and 45-day return policy. Check out the MU-601 on the Apos website here.
