Think of this week's episode as your comprehensive audio guide to the show floor. With so much in the offing the biggest challenge for anyone paying attention is choosing what to focus on. Our preview special breaks the Expo down into a handful of the most important themes we expect from this year's show. Our conversations cover the increasingly competitive world of wireless audio, the growing complexity of HDMI distribution, the continued blurring of lines between DIY and professionally installed products, and much more.
