Hi Mary Yes, strange as it seems, there are two digital inputs. The USB A (the bigger one) is for the little lightning connector, and is exclusively for Apple IOS devices. The USB B (the small slot) is for the little connecting cable which has a normal male USB A on the other end and is for Android USB On-The-Go devices or Windows or Apple PCs.
There must be a technical reason why IOS devices need that dedicated USB, probably the same reason you need to use a camera to USB connector to connect an IOS device to the USB input of the Chord DAC. That's the way it is though.

Hi John, So this comes with a short cable that has a lightning connector on one end and usb on the other which plugs into the headphone amp? Is that what you were saying? I guess I'm not getting why you'd need two different inputs into the amp, one for androids and one for i-devices. I certainly understand that the lightning connector and a usb are different, but those are the outs on the devices providing the source audio. When I last had a portable amp with dac was with the old 30-pin connector, and I can't remember how the cabling worked with that thing, did I buy an extra cable or what? Getting old isn't for the faint of heart. Mary Mary
