Hey everyone, I finally joined the forum after hours spent here reading. I want to get into higher quality music listening. I have been watching countless videos, reading, learning, etc and think I have narrowed down my choices of headphones down to the Shure SRH1540 and the Denon AH-D600.. They vary quite a bit in price but I think they are still comparable. Anyway, as of now, I am really leaning toward the 1540 due to them just being a bit higher in audio quality from what I read and watched on them vs the D600. Here's the reason I joined and am posting this - I went to a guitar center and tested a few pairs of Beyerdynamic 770 and 880 and a couple lower tier cans.. since I have no equipment yet, I plugged them straight to my iPhone 5.. and I was expecting it to be good sound but just quiet due to no amp... instead, I was completely turned off and bummed out by all of them. I got confused because my iPhone DID make it LOUD enough but it just sounded like the music was thin, far and very trebley.. I am 95% sure the problem is that I obviously had no amp.. but how is it that my iphone can make the headphones LOUD but sound so crappy? I have a pair of B&W C5s and LOVE them..very bassy and smooth. Obviously they sound far better than the beyers I tested because I didn't have an amp on them. But I am REALLY hoping that getting the right gear (Shure 1540 with Fiio E17 and E09k for desktop) will sound deep, heavy, creamy, rich, clear and almost cinematic. I want my music to sound rich and deep in bass.. I want slightly more quantity of bass than "normal" (not quite basshead level though) but I want the QUALITY of the bass to be GREAT, clean, rolling, and just beautiful. After 'demoing' the beyerdynamics, I was totally turned off.. again, I am sure it has to do with not having and amp but here is what I am looking for.. Someone please confirm for me that having an amp (particularly the two I want to buy E17&E09k) connected to the SRH 1540 or D600 will dramatically make them different than just straight through an ipod. I just want headphones that can sound cinematic and very rich across bass, mids, treble, overall. My plan is to get a very nice pair of headphones first and later scale them up with various amps, DAPs, Etc. So I am pretty confident the SRH1540 are the headphones I want but before I drop a small fortune on the gear, I NEED someone to alleviate my fear and CONFIRM that it IS in fact the amp that will make these things sound like I expect them to and that I am not just crazy for thinking the Beyers sounded awful un-amped (again, no offense to them, I am sure I am just hifi ignorant with no amp..) Thanks for the help in advance and for reading all of this! PS, Does the audio player I use on my desktop computer matter (itunes) if I play them through the e09k and e17? Or does the DAC and AMP just override everything?
