Is there a need for an iPad (Naim Uniti 2 owner.)

Hello,Is it possible to hear all BBC radio 3 programs that were broadcast the same day and one week earlier as I used to do on my B.M.C Dac 1.I do not own a iPad.As I have a NJC Monitor 2 headphone amplifier I have ordered the NJC Dac (192kHz) which via a usb cable will connect my iMac to the Dac,this system seams so much easier.I simple point the mouse to live BBC Radio 3 or there prevous weeks concerts or any music on the computer I wish to hear.So what I mean is can I listen to everything via a iPad as I have done in the past with just a iMac,Dac,Headphone amp,Headphones.Thanks.
