iPhone and MacBook Pro to Beomaster 2400?

Can anyone give me very specific advice on how to play music from my iPhone or MacBookPro through the Beomaster 2400? Novice here and would love some guidance. 

Buy this cable and connect it to the tape input

Or get an Airplay device/receiver and connect that with the input on the 2400.......same way as  Leo suggested.

Of course the AP receiver must be in the same home network as your iPhone/MacBook is.

Depending on the connection on the receiver the cable might be a bit different.

For actual advice which one, just ask Steve/SoundsHeavenly for advice.
