There are plenty of options out there if you're looking for an all-in-one connected media center and speaker system — but until now, there hasn't been one that so intriguingly combines old-school audio components with new-school connectivity and open-source computing. Meet the Tubecore Duo. It features the analog technology of a solid state amplifier and a dual vacuum tube preamp, coupled to a Raspberry Pi computer running XBMC media center. So what that gives you is a speaker system and streaming media hub with options to connect over Bluetooth, WiFi, HDMI, and component AV, letting you play music and video from virtually any source on-hand, and control it from your phone. Better still, the thing is gorgeous, with a handmade wood enclosure, a magnetic speaker grill available in a range of colors, and user-controllable LEDs in the tubes, this is a speaker system you're going to want to show off.
