We're all about ditching wires, but unfortunately most wireless speakers either lack performance or end up needing more wires than their wired alternatives. The KEF Wireless Audio System ($600) lets you use your existing speakers wirelessly, supplying 50 watts of power to each speaker, ensuring top-notch sound with HFADPCM technology, and eliminating the need for unsightly cords running from the front to the rear of your TV area.
