Hello? ? ? ? Is Anybody Home ?? ?

While I recognize that "PC Audio" may never compete with the excitement of SOTA home gear, isn't ANYBODY interested? I am not about to throw away my records for MP-3 files, but I am interested in further exploring PC based concepts, primarily for traveling. On that subject, does anyone know how I might get a line level signal from my Sony VAIO Z505 notebook to then output into a Headroom amplifier? Or do I have to use the cheesey internal amp and headphone jack which might defeat the purpose of using the amp and decent headphones in the first place? If I can get this thing to even sound half way listenable, movies and music on transatlantic flights might be a lot of fun. Thank you.
