FiiO L9 L-Shaped Line Out Dock (LOD) Cable For iPod and iPhone
Using this with ipod classic (7th gen) and ipod touch (4th gen) to portable amp. Sounds great and fits great. Also have L3 model with straight plug. Be aware the L3 has clips to lock it in place but otherwise sounds the same to me. So if you need straight wire with locking go for L3 but if you prefer right angle with a lower profile (sticks out less) go for this L9.
