You will most likely hear this from Ipod owners because amping the HP out of many Ipods will sound like doodoo. This led to the development of LOD cable which bypasses whatever makes the HP out sound like hell when amped. I don't use an Ipod anymore(I know I should change my username, but I've been lazy) I use Zunes(I like em,so I have a couple of em),I amp them using a mini to mini cable from the HP out. Sounds great! For the longest time I believed that I couldn't get top quality sound amping my player w/o using an LOD connection, taking what I'd read as gospel. I decided to try it anyway. I was wrong big time. I don't know if my lossless rips are better than everyone else's rips or what ,but I am stoked(Do people still use this word?)at how good my music sounds. There is absolutely no way I could go back to listening to no amp & IEMs.
