iPad as a music server?


Another thread suggested that the Camera Kit for the iPad bypassed the iPad's internal DAC. If this is the case, then couldn't the iPad be connected directly to an outboard DAC without the need for say the Wadia 170i dock?

The new Cambridge Audio iD100 ipad/iphone doc......as long as you have a dac. This should get around the usb problems and is cheaper than Wadia.
The upcoming iPad2, to be launched soon in March, will have a USB port and for those whose DAC's come with a USB input, using the iPad as a music server will be a much more pleasant experience. I wait with bated breath.
