I currently play my iPod through the Aux input of my intergrated amplifier/receiver. The problem is I have to turn the iPod volume up to about three-quarters (after that it distorts) and the stereo's volume up pretty loud too just to hear it at the volumes I'd listen to if this were a CD. Wondering if I should get a pre-amp. Would this improve the signal from the iPod and potentially improve the audio I'm getting out of this thing? Or should I just continue to use my CD player and give up on mp3 technology?
