Hi so I currently have an ipod nano (8g), and since I got a pair of Shure 530s I wanted a good player as well. My current music library is well over 8g (around 50 gb), and I cant decide if I should get a 32gb J3 with a 32gb micro SD card or an X7. I have heard much better things about the J3 than the X7, but I find it hard to pay $267 for a J3 when for $14 more on amazon I can get 160gb of space. I originally thought I needed the extra space but the X7 is a bit bulky, even though I mostly use it in my house, and seldomly carry it outside my house. Additionally I may remove some of my songs, since I dont listen to all of them and they are just taking up space. I download all my music in FLAC as well if that makes a difference.
