There are plenty of ways to get audio from one room in your home to another. You can wire for sound in every room or pick up a wireless audio system, but there are downsides and complications to both. The latest product from Aperion gives you the freedom of wireless audio and doesn't make you replace your audio components to do so.
The new Home Audio Link (HAL) is nice and easy to set up. Attach the transmitter to your source and hook the receiver up to what you want the sound to go to - speakers, a receiver or whatnot. The transmitter can attach via USB for computer audio, RCA, or through a headphone jack, giving you incredible flexibility for your source device. You can even use it to make your subwoofer wireless and get a bit more freedom in room placement. The one thing that may disappoint people about the HAL is that though you can buy multiple receivers to switch between, you're limited to a single transmitter. You can pick up the HAL system for $149. Additional receivers run $70.
