Tubecore Audio has announced the DUO; a tube-driven media streamer capable of intelligent human interaction and robotic control.
The DUO combines vintage style with modern design and hosts first in class features such as it's 48v integrated dual vacuum tube preamp and true RIAA phono input. The DUO is also the first home audio system to provide universal support for open-source embedded computing and feature the ability to stream all known media file types from all known devices, including uncompressed HiFi formats such as FLAC audio files via WiFi and Bluetooth.
DUO features a modular design that enables customers to infinitely modify and upgrade the system to suit their needs and support future technology upgrades, such as, communications advances with Bluetooth and WiFi streaming and DAC upgrades that support bit rates as high as 64 bit and 384 khz streaming.
It ships standard with the Raspberry Pi which enables the system to act as a HiFi media center capable of streaming HD movies and music via XBMC. DUO can also be upgraded to an advanced configuration thanks to a partnership with Seco to offer the UDOO board. This upgrade enables robotic control over the system's open-source hardware.
