Conclusion: The Pioneer A3 (XW-SMA3-K) is probably the most versatile wireless streaming speaker we've seen—it's even portable, rechargeable, and water resistant—but it doesn't sound like a $400 system.
Pros: Powerful audio for the size. Streams wireless audio via AirPlay, DLNA, HTC Connect, and Wireless Direct when there is no Wi-Fi signal. Water-resistant, portable, with rechargeable battery.
Cons: Distorts on deep bass tracks at top volumes. Very slow to power up. Overly complicated controls, and set up process is not terribly intuitive.
