“Audioengine claims the AW1’s can broadcast wireless audio up to 100 feet in “CD Quality Sound with no loss of quality”, and in our tests this was indeed the case. I was pleasantly surprised at how clean the audio sounded, as I had some less-than-stellar experiences with Bluetooth audio in the past, and my first Kima used FM radio to transmit its signal which was very prone to static and necessitated constant “channel scans” to find a clear spot. The AW1 transmits uncompressed PCM audio over an 802.11 network using a closed protocol specifically designed for audio, and the quality is identical to a hard wired connection. Additionally, there is zero latency with the AW1, meaning when you hit “NEXT” in iTunes, the next song begins playing instantly. It really works well.” —— macenstein.com
