@alexlhsu - The Nuforce iDo works great for me. Technically, i think it only "supports" gen 4-5 devices, but we also use gen 6 devices with it. I don't know if gen 7/8 devices will work, but I don't know why they wouldn't.
The iDo is long out of production and the availability is limited. Not sure if there is any comparable device that will connect to an iPhone/iPod and pass bit perfect digital...
Good luck.
