I promise you you will be quite happy with SR80's and an iPod. I ran my iPod Classic with just SR80's and loved it. I got curious and had the funds so I tried a portable amp and loved that too...I still listen to my SR80's 95% of the time with my portable setup.
If you're going to load your own CD's I would recommend you use ALAC or equvalent.
