Muse HiFi M6 Double Portable DAC & Headphone Amplifier

The World's Smallest Portable Electron Tube
Military-grade miniature, directly heated pentode NOS vacuum tubes. The JAN6418 imparts a warm, rich midrange with softened high-end overtones. We has spent three years developing two generations of products, significantly increasing the output power in tube mode, rivaling tube amplifiers.

Tube Shock Absorber Technology
We have devoted ourselves to the research and development of shock absorbers for JAN6418 electronic tubes, and designed a complete set of shock absorber solutions for JAN6418, including customized rubber components and component suspension technology, so that the electronic tubes can receive all-round buffering and absorption during use, and the current can be more stable.

The World's First Electron Tube + Nixie Tube Product
Developed using ESS's flagship chip platform, the "Double" architecture, specifically designed for both Electron Tube + Nixie Tube, took two years to design, Customized capacitor modules made of rare metals enhance the tube tone while stabilizing the 170V + 25V voltage, ensuring the M6Double operates at a stable temperature and strictly controlling heat generation.

We commissioned an open-source design from the chip manufacturer. We've taken the ES9039 to extremes, pairing it with two Accusilicon AS318B series chips running at 45.1584MHz/49.152MHz, a low-jitter, unified clock source. Custom circuitry deeply restructures the audio data. resulting in purer audio and a distinctly different sound experience between tube and transistor modes.
