Im using a nexus tablet ran to a RF 3sixty.3 processor. So i dont have a CD player. Im using usb audio over toslink optical to the processor so as to keep a full digital signal all the way back. For tuning purposes will it matter if i rip the tracks from the cd and convert them to audio files so my tablet can play them? Or can i use the various tuning tracks i already have that come with the RF 3sixty? would appreciate any type of advice on how to tune an oddball setup like this.
