You can connect an Apple Touch, iPad, or iPhone (non-wirelessly), using a CCK (Apple Camera Connection Kit) and a standard "USB Type A male" -to-" USB Type B male" cable, connected to the USB input of the HA-1, then use Spotify or Tidal apps, for example, to stream via Wifi. The iDevice would be "tethered," but it works really well and the iDevices have a very low noise floor compared to some other sources you might use with the HA-1's USB input (like a noisy laptop). The good news here, is that (I'm pretty sure) the HA-1's USB receiver is self-powered - it does not require the USB source to provide 5VDC - which the iDevices cannot do. They can only provide data, not power to a USB DAC. I use an Uptone Audio USB Regen to improve the USB signal quality right before it goes into a different DAC. If I'm incorrect in my recollection that the HA-1's USB input is self-powered, you could consider getting a USB Regen, which can supply very clean 5VDC power to USB receivers that are not self-powered, in addition to cleaning up the USB data.
