a SanDisk Sansa Clip+ with rockbox and a pair of really nice IEMs really is an ideal way to enjoy my music. size and weight of a postage stamp, clips to my shirt, doesn't require dealing with Phone Shit, plays my FLACs, has great sound quality, accepts a 256gb microSD card, battery lasts ages. it's perfect
edit: note: i'm currently trying it with a pair of Shure E5s, a truly ancient set of high-end dual-driver BA IEMs, and it's driving them very well despite the fact that they're 110-ohm phones. iirc it can drive even my 600-ohm HD540 References at a decent volume level if I crank it
