The DM-01 is a blast from a future that never was. Inspired by mid-century atomic-age aesthetics, this hybrid decoder merges vintage sci-fi design with 21st century audio tech. With a 12AU7 tube, a CS43131 DAC, and 1500mW of output power, it delivers rich analog warmth with digital precision. Bluetooth 5.4, USB DAC functionality, and a CNC-machined metal body make it a future-proof choice for your desktop audio setup.

Tube amplification for warm, vintage tone

The 12AU7 tube rounds out highs, enriches mids, and adds depth to bass frequencies. Whether you’re spinning vinyl rips or streaming lossless files, the DM-01 gives everything a smooth, organic character.

Power for serious headphones

With 1500mW of output power, the DM-01 can drive everything from efficient IEMs to 600Ω studio headphones.

High-resolution decoding with pro-grade DAC

Decoding is handled by a CS43131 DAC, supported by an XMOS XU316 16-core chip. This setup ensures precise digital-to-analog conversion, handling PCM up to 32-bit/384kHz, DSD256, and MQA 8X decoding. Expect deep detail retrieval and a broad, immersive soundstage.

Hybrid architecture for the best of both worlds

A combination of tube amplification and transistor buffering balances vintage warmth with fast transient response. The result is a sound signature that’s lush yet detailed.

Bluetooth 5.4

Featuring the latest Qualcomm Bluetooth 5.4 chip, the DM-01 supports aptX HD, aptX Adaptive, LDAC, and LE Audio formats. This means lower latency, improved wireless stability, and high-resolution audio playback without the hassle of cables.

At-a-glance status updates

With the DM-01’s LED indicator system, you can instantly check your playback and connection status. The color-coded system provides real-time updates on sampling rates and Bluetooth codecs, so you always know what’s running.
