Hey raybone, don't even try, 40+ hours aa bateries guy is just like that, he ask for 40+ hours of battery life, but then he says that if X player is over 90 hours, he'll "probably" buy it, I think most of us know where we are, in an audiophile forum and know that high quality (in everything) costs money, and then there's a guy that wants sooo much from a $50 player and he's the only one in his quest for aa batteries that really it's not even funny anymore, he asks for a cheap player that uses aa batteries but wants so much from it, you get what you pay for dude, and everyone here gets it except for just one guy (we know who), and if you are just waiting for your dream player that use your precious aa batteries with it's 40+ hours, hd radio, supreme earbuds, small and big at the same time, with rockbox as ui, 2 card slots, aluminum case and case with clip for under $100 (that you'll "probably" buy), come on buddy, the M3 will cost $50, that's a pizza, wings and a pepsi, just get it or don't, or keep waiting for that aa bateries player that you want so much, I'm sure fiio will do it for you, right? like you said, it's the "least worst", and stop repeating the same over and over about those aa batteries/40+ hours and asking so much for a player that, from an audiophile point of view, costs next to nothing.
