Hi everybody. I just got my new Audio GD Rig. I would like to steam and play recorded music from my iPad. I have a Optical, coax, and USB type B input on the DAC. That being said what is the best way to hook up my iPad? To my knowledge there is no single cord that will work. It involves adapters and such. I have never used a Digital coax input before so I am clueless about that Input. Thanks for your help!
