The Qudelix-5K is a Bluetooth-capable USB DAC/Amp that fits right in your pocket (or right outside it, with a built-in clip) that won’t require you to compromise on resolution and performance. The unit is powered by a Qualcomm QCC5124 quad-core processor that delivers Bluetooth 5.0 transmission functionality and excellent computational performance. That’s paired with dual ES9219 SABRE high-fidelity chips to round things out on the resolution front. What that all amounts to is 24Bit, 96KHz decoding along with full support for top-tier Bluetooth codecs like LDAC, aptX adaptive and HD, as well as AAC. On the output side, you’ll find balanced 2.5-millimeter connections that can provide 4V RMS, or a 3.5-millimeter unbalanced option with 2V RMS functionality. Plus, when you fire up the Qudelix app (available on Android and iOS devices) you can bring together an incredibly powerful 20-band equalizer. This gives you fully functional I/O and tons of flexibility—making the Qudelix-5K the perfect little DAC and headphone amp to toss right into your pocket.
