Pioneer used the CEDIA expo today to dip into bookshelf-sized iPhone and iPod speakers for the first time in the US. Having just entered Europe a week ago, the XW-NAS3 and XW-NAS5 are both single-piece units but are designed for better sound than usual in the class with 2.1-channel, digitally amped 60W output. They both also have stealth displays behind the grill and optionally support Bluetooth for streaming stereo music, including from an iPhone or iPod touch.
