I don't but go to an audiophile website and mention that you use an iPod with a stereo system that costs thousands of dollars and see what they will say about it.In a word, capacity. Also convenience. iPods integrate so easily with car stereos and other docking devices. At home, where I can really get the best audio, I don't use an ipod.
Do you have a suggestion?
It's just funny hearing people say they are so concerned about audio using an iPod.
