I was hoping that connecting my iPhone 6 to my Harman Kardon 330c was as easy as using an RCA cable to connect the phone into the AUX in the back of the receiver. I hear the music, but I have to crank the volume on the iPhone 6 all the way up and have to crank the volume of the receiver way up as well. Is this what a DAC is for? Is there a solution that doesn't cost so much? I'm just looking to stream an online music service through my home stereo.
