I'm new to the world of hi-fi (as well as this website), and, as such, I'm looking for a relatively cheap set-up to get me started. Nothing fancy, but I want maximum bang-for-the-buck. As of now, I'm thinking of getting a headroom bithead headphone amp (which I'll be able to use with my laptop, but aslo with my ipod) and a set of Audio Technica ATH-A700's (or possibly ATH-M50's). Just want some general feedback. Will this set-up provide me with the kind of high quality audio that I want? I'm open to suggestions for other headphones ~$150, or if there's a better option to get me reasonably good sound quality under $400 then I'd be interested in hearing about it.
