Hi! Joined not 10 minutes ago, though i've been reading topics and reviews on headphones for a while. Hope my inexperience doesn't bother some. Alright, so i bought a pair of Senheiser HD439 about a month and a half back. I've been using them with an Ipod touch 4th gen, without an amp. They sound pretty good, certainly better than the previous Senheiser HD202 i had before.... but i feel like i need to raise the volume too high for them to sound full. This didn't happen with a pair of Sony earbuds i have, so i've come to the conclusion that i need an amp. My budget is 40 dollars, i have heard and looked at the Fiio E6, but two opinions are better than one. So if you guys could give me you're opinion on if that's the best option under 40 dollars? Or anything i should know that i'm missing to improve the sound? I've heard that switching to leather cups on the HD439's gives a warmer sound and improves noise isolation... true? And i shouldn't leave this out: I'm getting an Ipod Touch 5th generation in a few weeks. The lightning connetor is not compatible with the line out cable Fiio has for the E6, will it be worth it without a line-out cable? Or should i wait until lightning line-out cables appear? Thanks in advance!
