Philips HTL9100: Detachable, battery-powered rear speakers
Samsung stuffs tubes in a sound bar
Samsung's obsession with tubes started with last year's CES darling, the DA-E750, and now the company is adding vacuum tube amplifiers to home theater systems and even sound bars. The Samsung HW-F750 is dubbed the "world's first sound bar with a vacuum tube amp," which is technically true: like last year's models, it has a tube preamplifier paired with a digital amplifier.
Also cool: it can connect wirelessly to certain Samsung TVs, for the most clutter-free sound bar look yet.
