I joined head-fi intending to get new IEMs, but I just found my old ER6s. They still sound pretty good, but I was wondering whether I'd get better sound with an amp/DAC or if I should just get new IEMs after all. My source is an iAudio 9. Will an amp make any difference? I notice there's not a line out and that seems important to get the most out of an amp, from what I've been reading.
Thanks for any suggestions
