so i just pulled the trigger on a pair of IE8s and i must say im extremely excited. i will be doing my listening from an ipod classic, iphone 4, and mac book pro. i have one of those altoids amps i purchased for a set of Sennheiser over ears that i no longer own. what else do i need so that i can actually enjoy my IEMs the way they should be enjoyed? im considering getting custom tips from listenhear. but what about DACs and other stuff? thanks guys!
