This simple question kept us motivated and led to the creation of two of the smallest products we've ever offered - WA8 Eclipse and WA11 Topaz. But the pursuit to go smaller continues. In late 2019, we created a powerful solid-state amp that is pocketable but we felt it was missing our vacuum tube roots. A eureka moment came when we placed the Eclipse and the Topaz amps side by side; we thought, “can we engineer a portable vacuum tube amp\/DAC based on these two products?” Excited about the possibility, we focused our engineering efforts on achieving this vision.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Woo Audio TUBE mini Portable USB DAC\/amp In Hand\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/20230616_203856_1024x1024.jpg?v=1695740262\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eIntroducing\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe all-new TUBE mini is an ultraportable vacuum-tube headphone amplifier and DAC that delivers an Impressively powerful sound in half the size of the average smartphone.

The result is the warm sound of vacuum tubes and the superpower of MOSFET amplification for an effortless sound that comes alive with full-sized headphones. There are three technologies working seamlessly in TUBE mini - a power management system for plug-and-play setup, a tube headphone amplifier, and a high-resolution lossless DAC; all in an impossibly small design. \u003c\/p\u003e\n\u003cp\u003eOn full display are the vacuum tubes. Each tube is designed to amplify one channel (hence a pair for left\/right stereo) combined with the powerhouse of MOSFET in a balanced architecture we call Mighty-Drive. The result is a unique sound not found in any solid-state or small tube amps.\u003c\/p\u003e\n\u003cp\u003eVacuum tube technology has been in use since the early 1900s for a wide range of applications from audio \/ video consumer equipment, to medical imaging, to mission-critical military devices. Tubes are robust and maintenance-free, capable of many thousands of hours of operation.\u003c\/p\u003e\n\u003cp\u003eIn audio component applications, tube microphonics from external mechanical vibrations can transfer to the tungsten heaters and thus become audible in the signal path. In order to reduce mechanical vibration, the tubes in TUBE mini are intricately mounted on a spring-loaded suspension system similar to seismic damper systems found in earthquake protection measures.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eSignature Sound\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe internal ESS SABRE DAC is optimized for streaming music services and lossless playback of all Hi-Res formats.
