FYI, you don't need to use all caps in your thread title, and maybe edit it to make your question clear?
The Ed. 8 sounds fine straight out of an iPod, but if you don't plan to use/get a portable amp or a DAP with a high-quality amp built in (like the HiFiMAN HM-801), then I don't think the Ed. 8 is worth the cost for you. Unamped from an iPod, the Ed. 8 sounds slightly flat, probably better than any other closed-headphone, but certainly not close to a $1300 difference over the D2000 or ESW9.
If you really don't want to get an amp, I'd suggest the ESW9 or D2000. But if you have the money for the Ed. 8, get it used or find a deal (use the coupon at rmcaudiodirect.com) and spend the extra money on a portable amp or the HM-801. The Ed. 8 really sings with decent amping; it sounds magical from the HM-801's headphone out.
