Unboxing and Design
The XDUOO XBOT DM-01 arrived in a package containing the DAC/amp itself, a USB Type-C cable, a power supply, and some stickers. The price point sits at $279. The design is undeniably retro, evoking a playful, almost whimsical aesthetic with its robot-like appearance. This quirky design might not appeal to everyone, but it's certainly a conversation starter and adds a unique touch to any desktop setup.
The build quality is surprisingly robust for its price. It feels substantial and stable, thanks to its weight distribution, preventing accidental tipping. The LED indicators in the 'eyes' change color based on sampling rate and volume, adding an extra layer of visual feedback.
Features and Controls
The XBOT DM-01 boasts clever features beyond its looks. The robot arms aren't just for show; raising the right arm powers the device on and reveals a 6.35mm headphone output. The arm's position also controls input selection: down for standard input, middle for Bluetooth pairing, and up for USB input. These intuitive physical controls enhance user experience.
Connectivity options are comprehensive, including Bluetooth 5.4 with various codecs (AAC, SBC, aptX, aptX Adaptive, aptX HD, LDAC), USB Type-C audio input, a 6V auxiliary output for external speakers, and a top-mounted tube socket for easy tube swapping.
Sound Quality and Performance
The DM-01, using a CS43131 DAC chip, handles up to 32-bit PCM and DSD256. Its 1.5-watt output at 32 ohms drives a wide range of headphones, from IEMs to high-impedance full-sized cans with ease, though some background hiss was noticeable with sensitive IEMs. The sound signature with the stock 12AU7 tube is fairly neutral with a touch of warmth, perhaps less overtly 'tuby' than anticipated.
Compared to solid-state amplifiers, the DM-01's tube characteristics are more pronounced. It offers a surprising amount of detail and clarity in the upper mids and treble, alongside a decent soundstage. However, the mid-bass and lower mid-range presented a slightly more linear tonality than expected for a tube amp. Despite some minor shortcomings, the overall sound is enjoyable.
Tube Rolling and Conclusion
Experimenting with PSvane Horizon 12AU7 ATS tubes ($30 each) resulted in a leaner, less warm sound with a slightly brighter, more energetic treble. This added crispness enhanced percussion and created a more open sound, though it might not appeal to those seeking exceptionally warm tonality. This tube rolling option offers another layer of customization and experimentation.
Overall, the XDUOO XBOT DM-01 is a competent and versatile DAC/amp at its price point. Its sound quality is impressive, offering a good balance between neutrality, detail, and a touch of tube warmth. The unique design is a bonus, but the sound alone justifies its purchase. While not the warmest tube amp, it's a solid entry point for those interested in exploring the world of tube amplification.
