FiiO L9 L-Shaped Line Out Dock (LOD) Cable For iPod and iPhone
You wouldn't think this cable would really make a difference when your hooking up your iPod or iPhone to a portable amp. But it really does make a difference. Normally you'd let your device/mp3 player decode your music to analog before feeding it to the next device but the newer amps/DACs do a much better job decoding ad converting to analog that it's just better sense to let it do its job. No more noisy lines and a much cleaner signal.  Just buy the cable and try it for yourself. Then you'll be happy you i
