Hi everyone, first time poster here. I've enjoyed the forum & it's incredible community for some time now and can finally enter the foray of higher-end audio. Recently some deals have come my way on the following pieces so I'm stuck trying to choose between them. Suggestions on any other cans are of course welcome as well. Deals: -BeyerDynamic T1's, slightly used by a friend, for $800 -Sony MDR-CD3000, found here: http://www.head-fi.org/forum/thread/564542/headphones-sony-mdr-cd3000-woodied-akg-k340-woodied-and-koss-ksc-35 -Audio Technica ATH-W5000, also slightly used by a friend, for $500 I'm aware that these cans have many intrinsic differences and that "better" is highly subjective, just looking for some general opinions really. It may be worth noting I haven't purchased a serious, relevant amp yet, so "matching" doesn't have to be taken into consideration. Amp budget is about $600 & am open to suggestions in that arena as well. Thanks very much guys, your input is appreciated!
