More power and detail. I'd suggest you check out the Nationite s:flo2 aka Telecast T51.
Read up on some of it's downfalls (battery life, not the most user friendly UI, no gappless, etc) and seriously think if you are willing to try it/think you would be able to live with it. There is no doubting this is a fantastic sounding player for the price, but it's not perfect.
EDIT: And yes I think the s:flo2 would be worth the money, you should be able to notice the difference in sound quality. I certainly can compared to my rockboxed Clip+.
