Hello, I have been told that a ipod line-output adapter will give me a better sound when used with my Headphone Amp connected to my ipod, where do I buy one from ? Thanks.
Alternatively, any iPod dock will do the job, such as the Cambridge Audio ID10, currently £15 at Richer Sounds. Another tenner will let you add the IP10 remote control to 'drive' the iPod.
Other alternatives to look at are the iBasso CB03 and search 'line out dock' on ebay and you may find that same cable for a bit less and numerous alternatives. But as for quality and functionality I can vouch for the above recommended GQ-24 and iBasso.
