Ok guys I just got my fiio e6 and after charging it and plugging it in to my phone I can say that it satisfies with the volume boost BUT it does not infact make the SQ better, actually it seems to slightly show just how terrible some of my files sound. Well I can convert my files to 320kpbs until I can buy music from CDs but overall I'm happy with this 33 dollar investment (12 dollar 2 shipping day fee)
Upconverting won't do you any good. If anything, it'll make things worse if your encoder is bad. Wait for CDs...umm...Spotify has some decent free music at 320kbps (I think they have free accounts...I'm too lazy to look).
