I really advise against the Etys out of your laptop. I don't consider myself to have extremely acute hearing, and it really kills me to listen to any good headphones out of a computer's jack. Granted, I haven't tried it with an external DAC, but I don't see how that could possibly eliminate all the noise -- and any little bit is going to shine through very clearing with the 4P, from what I hear. And if you're planning on listening to downloaded MP3 files, which I assume you are or you'd also have the music on CD, that's another reason not to buy the Etys. If you've ever listened to MP3 audio on good 'phones, even ones that are ripped well (which downloaded ones usually are not), it doesn't sound so good. Etys will bring out every flaw.
I'm thinking of cashing in my mini-system and going for the NS500V setup for my dorm next year. I might bring along some small speakers, but I'm rapidly converting to being primarily a headphone user, so maybe I'll ditch speakers too. The things I've heard about the NS500V lead me to believe that I'll be able to hang onto it for a while and build a pretty good system around it. Works for me, especially at the price.
