I say there is some kind of difference betwee the fuze and clip. Although most people say that they sound identical, I somehow feel that the fuze is just a miniscule tad warmer sounding than the clip (the original in v1). When the clip+ came out I was really excited as I loved the clip, but then I did notice everyone saying that it was warmer so I was (and am) hesitant about it. I think for my ears which are used the sound of a clip with v1 firmware, I better source a 8gb one XD;
