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.
Our computers, tablets, and phones are capable of accessing unimaginable libraries of music. Unfortunately, they're not so good at driving serious headphones to let you hear all the nuances of said tunes. But add in the McIntosh MHA100 Headphone Amplifier, and you're ready to rock. It can handle cans from 8-600 ohms, virtually guaranteeing compatibility, and features a Headphone Crossfeed Director that makes those speakers on your head image like studio monitors, plus four digital inputs, two analog inputs, and 50 watt speaker outputs for when you feel like annoying the entire office with the Quad City DJ's "Space Jam".
