The Onkyo UBT-1, which is similar in size to a USB flash drive, plugs into the frontUSBport of a 2012 Onkyo Network receiver (models TX-NR414 and higher).
Offering a refined take on the category, this system features a powerful 5.1-channel receiver with AirPlay and a front panel USBport for direct connectivity to iPhones, iPads, iPods and USB drives.
Just as the name suggests, the device comes in the shape of a cube, with an IR receiver on the front side, a USBport on the right, and a bunch more on the back: HDMI-in, HDMI-out, another USBport, RJ-45 and IR-out.
